TheLT1638/LT1639opampsoperateonallsingleandsplit
supplies with a total voltage of 2.5V to 44V drawing only
170μA of quiescent current per amplifier. These ampli-
fiers are reverse battery protected and draw no current
for reverse supply up to 18V.
No Phase Reversal
Available in 14-Lead SO, 8-Lead MSOP and DFN
Packages
The input range of the LT1638/LT1639 includes both sup-
plies, and a unique feature of this device is its capability
to operate over the top with either or both of its inputs
+
APPLICATIONS
above V . The inputs handle 44V, both differential and
common mode, independent of supply voltage. The input
stage incorporates phase reversal protection to prevent
false outputs from occurring when the inputs are below
the negative supply. Protective resistors are included in
the input leads so that current does not become excessive
when the inputs are forced below the negative supply.
The LT1638/LT1639 can drive loads up to 25mA and still
maintain rail-to-rail capability. The op amps are unity-gain
stable and drive all capacitive loads up to 1000pF when
optional output compensation is used.

APPLICATIONS INFORMATION
Supply Voltage
The inputs are protected against excursions of 2V below
–
V by an internal 1k resistor in series with each input and
The positive supply pin of the LT1638/LT1639 should be
bypassed with a small capacitor (typically 0.1μF) within an
inchofthepin.Whendrivingheavyloadsanadditional4.7μF
electrolytic capacitor should be used. When using split
supplies, the same is true for the negative supply pin.
a diode from the input to the negative supply. If the inputs
–
can go more than 2V below V , an additional external
resistor is required. A 10k resistor will protect the input
–
against excursions as much as 10V below V . The input
stage of the LT1638/LT1639 incorporates phase reversal
protection to prevent the output from phase reversing for

–
inputs below V . There are no clamping diodes between
the inputs and the maximum differential input voltage is
44V.
+
The LT1638/LT1639 can be shut down by removing V .
In this condition the input bias current is less than 0.1nA,
even if the inputs are 44V above the negative supply.
Output
The output of the LT1638/LT1639 can swing within 20mV
of the positive rail with no load, and within 3mV of the
negative rail with no load. When monitoring voltages
within 20mV of the positive rail or within 3mV of the
negative rail, gain should be taken to keep the output from
clipping. The LT1638/LT1639 are capable of sinking and
sourcing over 40mA on 15V supplies; sourcing current
capability is reduced to 20mA at 5V total supplies as noted
in the electrical characteristics.
When operating the LT1638/LT1639 on total supplies of
10V or more, the supply must not be brought up faster
than 1V/μs. Increasing the bypass capacitor and/or add-
ing a small resistor in series with the supply will limit the
rise time.
Inputs
The LT1638/LT1639 have two input stages, NPN and PNP
(see the Simplified Schematic), resulting in three distinct
operating regions as shown in the Input Bias Current vs
Common Mode typical performance curve.
The LT1638/LT1639 are internally compensated to drive
at least 200pF of capacitance under any output loading
conditions. A 0.22μF capacitor in series with a 150Ω
resistor between the output and ground will compensate
these amplifiers for larger capacitive loads, up to 1000pF,
at all output currents.
+
For input voltages about 0.8V or more below V , the PNP
input stage is active and the input bias current is typically
–20nA. When the input common mode voltage is within
0.5V of the positive rail, the NPN stage is operating and
the input bias current is typically 40nA. Increases in tem-
peraturewillcausethevoltageatwhichoperationswitches

The application in Figure 3 utilizes the Over-The-Top

TYPICAL APPLICATION
The battery monitor in Figure 5 also demonstrates the
LT1638’s ability to operate with its inputs above the
positive rail. In this application, a conventional amplifier
would be limited to a battery voltage between 5V and
ground, but the LT1638 can handle battery voltages as
high as 44V. When the battery is charging, Amp B senses
the voltage drop across RS. The output of Amp B causes
Q2 to drain sufficient current through RB to balance the
input of Amp B. Likewise, Amp A and Q1 form a closed
loopwhenthebatteryisdischarging. Thecurrentthrough
Q1 or Q2 is proportional to the current in RS and this cur-
rent flows into RG and is converted into a voltage. Amp
D buffers and amplifies the voltage across RG. Amp C
compares the output of Amp A and Amp B to determine
the polarity of current through RS. The scale factor for
VOUT with S1 open is 1V/A. With S1 closed the scale
factor is 1V/100mA and currents as low as 500μA can
be measured.
