GENERAL DESCRIPTION
APPLICATIONS
ALD114804/ALD114804A/ALD114904/ALD114904Aare high precision monolithic
quad/dual depletion mode N-Channel MOSFETS matched at the factory using
ALD’s proven EPAD® CMOS technology. These devices are intended for low
voltage, small signal applications. They are excellent functional replacements for
normally-closed relay applications, as they are normally on (conducting) without
any power applied, but could be turned off or modulated when system power
supply is turned on. These MOSFETS have the unique characteristics of, when
the gate is grounded, operating in the resistance mode for low drain voltage lev-
els and in the current source mode for higher voltage levels and providing a
constant drain current.
• Functional replacement of Form B (NC) relays
• Ultra low power (nanowatt) analog and digital
circuits
• Ultra low operating voltage (<0.2V) analog and
digital circuits
• Sub-threshold biased and operated circuits
• Zero power fail safe circuits in alarm systems
• Backup battery circuits
• Power failure and fail safe detector
• Source followers and high impedance buffers
• Precision current mirrors and current sources
• Capacitives probes and sensor interfaces
• Charge detectors and charge integrators
• Differential amplifier input stage
• High side switches
ALD114804/ALD114804A/ALD114904/ALD114904A MOSFETS are designed for
exceptional device electrical characteristics matching. As these devices are on
the same monolithic chip, they also exhibit excellent temperature tracking char-
acteristics. They are versatile as design components for a broad range of analog
applications, such as basic building blocks for current sources, differential ampli-
fier input stages, transmission gates, and multiplexer applications.
• Peak detectors and level shifters
• Sample and Hold
• Current multipliers
• Discrete analog switches and multiplexers
• Discrete voltage comparators
Besides matched pair electrical characteristics, each individual MOSFET also
exhibits well controlled parameters, enabling the user to depend on tight design
limits corresponding to well matched characteristics.
These depletion mode devices are built for minimum offset voltage and differen-
tial thermal response, and they are suitable for switching and amplifying applica-
tions in single supply (0.4V to + 5V ) or dual supply (+/- 0.4V to +/-5V) systems
where low input bias current, low input capacitance and fast switching speed are
desired. These devices exhibit well controlled turn-off and sub-threshold
charactersitics and therefore can be used in designs that depend on sub-thresh-
old characteristics.

The ALD114804/ALD114804A/ALD114904/ALD114904A are suitable for use in
precision applications which require very high current gain, beta, such as current
mirrors and current sources. A sample calculation of the DC current gain at a
drain current of 3mA and gate input leakage current of 30pA = 100,000,000. It is
recommended that the user, for most applications, connect the V+ pin to the
most positive voltage and the V- and IC pins to the most negative voltage in the
system. All other pins must have voltages within these voltage limits at all times.

PERFORMANCE CHARACTERISTICS OF EPAD®
PRECISION MATCHED PAIR MOSFET FAMILY
ALD1108xx/ALD1109xx/ALD1148xx/ALD1149xx are monolithic
currents and channel/junction leakage currents. When negative
signal voltages are applied to the gate terminal, the designer/user
can depend on the EPAD MOSFET device to be controlled, modu-
lated and turned off precisely. The device can be modulated and
turned-off under the control of the gate voltage in the same manner
as the enhancement mode EPAD MOSFET and the same device
equations apply.
quad/dual N-Channel MOSFETs matched at the factory usingALD’s
proven EPAD® CMOS technology. These devices are intended for
low voltage, small signal applications.
ALD’s Electrically Programmable Analog Device (EPAD) technol-
ogy provides the industry’s only family of matched transistors with
a range of precision threshold values. All members of this family
are designed and actively programmed for exceptional matching of
device electrical characteristics. Threshold values range from -
3.50V Depletion to +3.50V Enhancement devices, including stan-
dard products specified at -3.50V, -1.30V, -0.40V, +0.00V, +0.20V,
+0.40V, +0.80V, +1.40V, and +3.30V. ALD can also provide any
customer desired value between -3.50V and +3.50V. For all these
devices, even the depletion and zero threshold transistors, ALD
EPAD technology enables the same well controlled turn-off, sub-
threshold, and low leakage characteristics as standard enhance-
ment mode MOSFETs. With the design and active programming,
even units from different batches and different date of manufacture
have well matched characteristics. As these devices are on the
same monolithic chip, they also exhibit excellent tempco tracking.
EPAD MOSFETs are ideal for minimum offset voltage and differen-
tial thermal response, and they are used for switching and amplify-
ing applications in low voltage (1V to 10V or +/-0.5V to +/-5V) or
ultra low voltage (less than 1V or +/- 0.5V) systems. They feature
low input bias current (less than 30pA max.), ultra low power
(microWatt) or Nanopower (power measured in nanoWatt) opera-
tion, low input capacitance and fast switching speed. These de-
vices can be used where a combination of these characteristics
are desired.
KEY APPLICATION ENVIRONMENT
EPAD( MOSFET Array products are for circuit applications in one
or more of the following operating environments:
* Low voltage: 1V to 10V or +/- 0.5V to +/- 5V
This EPAD MOSFETArray product family (EPAD MOSFET) is avail-
able in the three separate categories, each providing a distinctly
different set of electrical specifications and characteristics. The first
* Ultra low voltage: less than 1V or +/- 0.5V
* Low power: voltage x current = power measured in microwatt
* Nanopower: voltage x current = power measured in nanowatt
* Precision matching and tracking of two or more MOSFETs
category is the ALD110800/ALD110900 Zero-Threshold™ mode
EPAD MOSFETs. The second category is the ALD1108xx/
ALD1109xx enhancement mode EPAD MOSFETs. The third cat-
egory is the ALD1148xx/ALD1149xx depletion mode EPAD
MOSFETs. (The suffix “xx” denotes threshold voltage in 0.1 V steps,
for example, xx=08 denotes 0.80V).
ELECTRICAL CHARACTERISTICS
The turn-on and turn-off electrical characteristics of the EPAD
MOSFET products are shown in the Drain-Source On Current vs
Drain-Source On Voltage and Drain-Source On Current vs Gate-
Source Voltage graphs. Each graph show the Drain-Source On
Current versus Drain-Source On Voltage characteristics as a func-
tion of Gate-Source voltage in a different operating region under
different bias conditions. As the threshold voltage is tightly speci-
fied, the Drain-Source On Current at a given gate input voltage is
better controlled and more predictable when compared to many
other types of MOSFETs.
The ALD110800/ALD110900 (quad/dual) are EPAD MOSFETs in
which the individual threshold voltage of each MOSFET is fixed at
zero. The threshold voltage is defined as I = 1uA @ V = 0.1V

PERFORMANCE CHARACTERISTICS OF EPAD®
PRECISION MATCHED PAIR MOSFET FAMILY (cont.)
ZERO TEMPERATURE COEFFICIENT (ZTC) OPERATION
SUB-THRESHOLD REGION OF OPERATION
For an EPAD MOSFET in this product family, there exist operating
points where the various factors that cause the current to increase
as a function of temperature balance out those that cause the cur-
rent to decrease, thereby canceling each other, and resulting in net
temperature coefficient of near zero. One of this temperature stable
operating point is obtained by a ZTC voltage bias condition, which
Low voltage systems, namely those operating at 5V, 3.3V or less,
typically require MOSFETs that have threshold voltage of 1V or
less. The threshold, or turn-on, voltage of the MOSFET is a voltage
below which the MOSFET conduction channel rapidly turns off. For
analog designs, this threshold voltage directly affects the operating
signal voltage range and the operating bias current levels.
is 0.55V above a threshold voltage when V
= V , resulting in a
GS
DS
temperature stable current level of about 68uA. For other ZTC op-
erating points, see ZTC characteristics.
At or below threshold voltage, an EPAD MOSFET exhibits a turn-
off characteristic in an operating region called the subthreshold re-
gion. This is when the EPAD MOSFET conduction channel rapidly
turns off as a function of decreasing applied gate voltage. The con-
duction channel induced by the gate voltage on the gate electrode
decreases exponentially and causes the drain current to decrease
exponentially. However, the conduction channel does not shut off
abruptly with decreasing gate voltage, but decreases at a fixed rate
of approximately 116mV per decade of drain current decrease. Thus
if the threshold voltage is +0.20V, for example, the drain current is

Performance characteristics of the EPAD MOSFET product family
are shown in the following graphs. In general, the threshold voltage
shift for each member of the product family causes other affected
electrical characteristics to shift with an equivalent linear shift in

When supply voltages decrease, the power consumption of a given
load resistor decreases as the square of the supply voltage. So
one of the benefits in reducing supply voltage is to reduce power
consumption. While decreasing power supply voltages and power
consumption go hand-in-hand with decreasing usefulAC bandwidth
and at the same time increases noise effects in the circuit, a circuit
designer can make the necessary tradeoffs and adjustments in any
given circuit design and bias the circuit accordingly.

MATCHING CHARACTERISTICS
A key benefit of using matched-pair EPAD MOSFET is to maintain
temperature tracking. In general, for EPAD MOSFET matched pair
devices, one device of the matched pair has gate leakage currents,
junction temperature effects, and drain current temperature coeffi-
cient as a function of bias voltage that cancel out similar effects of
the other device, resulting in a temperature stable circuit. As men-
tioned earlier, this temperature stability can be further enhanced by
biasing the matched-pairs at Zero Tempco (ZTC) point, even though
that could require special circuit configuration and power consump-
tion design consideration.
With EPAD MOSFETs, a circuit that performs a specific function
can be designed so that power consumption can be minimized. In
some cases, these circuits operate in low power mode where the
power consumed is measure in micro-watts. In other cases, power
dissipation can be reduced to nano-watt region and still provide a
useful and controlled circuit function operation.
