SPECIFIC ADVANTAGES OF 5-Pin SOT-23 (TinyPak)
Application Information
The obvious advantage of the 5-pin SOT-23, TinyPak, is that
it can save board space, a critical aspect of any portable or
miniaturized system design. The need to decrease overall
system size is inherent in any handheld, portable, or
lightweight system application.
GENERAL INFORMATION
Low supply current and wide bandwidth, greater than rail-to-
rail input range, full rail-to-rail output, good capacitive load
driving ability, wide supply voltage and low distortion all make
the LM7341 ideal for many diverse applications.
Furthermore, the low profile can help in height limited designs,
such as consumer hand-held remote controls, sub-notebook
computers, and PCMCIA cards.
The high common-mode rejection ratio and full rail-to-rail in-
put range provides precision performance when operated in
non-inverting applications where the common-mode error is
added directly to the other system errors.
An additional advantage of the tiny package is that it allows
better system performance due to ease of package place-
ment. Because the tiny package is so small, it can fit on the
board right where the op amp needs to be placed for optimal
performance, unconstrained by the usual space limitations.
This optimal placement of the tiny package allows for many
system enhancements, not easily achieved with the con-
straints of a larger package. For example, problems such as
system noise due to undesired pickup of digital signals can
be easily reduced or mitigated. This pick-up problem is often
caused by long wires in the board layout going to or from an
op amp. By placing the tiny package closer to the signal
source and allowing the LM7341 output to drive the long wire,
the signal becomes less sensitive to such pick-up. An overall
reduction of system noise results.
CAPACITIVE LOAD DRIVING
The LM7341 has the ability to drive large capacitive loads. For
example, 1000 pF only reduces the phase margin to about 30
degrees.
POWER DISSIPATION
Although the LM7341 has internal output current limiting,
shorting the output to ground when operating on a +30V pow-
er supply will cause the op amp to dissipate about 350 mW.
This is a worst-case example. In the 5-pin SOT-23 package,
the higher thermal resistance will cause a calculated rise of
113°C. This can raise the junction temperature to above the
absolute maximum temperature of 150°C.
Often times system designers try to save space by using dual
or quad op amps in their board layouts. This causes a com-
plicated board layout due to the requirement of routing several
signals to and from the same place on the board. Using the
tiny op amp eliminates this problem.
Operating from split supplies greatly reduces the power dis-
sipated when the output is shorted. Operating on ±15V sup-
plies can only cause a temperature rise of 57°C in the 5-pin
SOT-23 package, assuming the short is to ground.
Additional space savings parts are available in tiny packages
from National Semiconductor, including low power amplifiers,
precision voltage references, and voltage regulators.
WIDE SUPPLY RANGE
The high power-supply rejection ratio (PSRR) and common
mode rejection ratio (CMRR) provide precision performance
when operated on battery or other unregulated supplies. This
advantage is further enhanced by the very wide supply range
(2.5V–32V) offered by the LM7341. In situations where highly
variable or unregulated supplies are present, the excellent
PSRR and wide supply range of the LM7341 benefit the sys-
tem designer with continued precision performance, even in
such adverse supply conditions.
LOW DISTORTION, HIGH OUTPUT DRIVE CAPABILITY
The LM7341 offers superior low-distortion performance, with
a total-harmonic-distortion-plus-noise of −66 dB at f = 10 kHz.
The advantage offered by the LM7341 is its low distortion
levels, even at high output current and low load resistance.

Typical Applications
HANDHELD REMOTE CONTROLS
The LM7341 offers outstanding specifications for applications
requiring good speed/power trade-off. In applications such as
remote control operation, where high bandwidth and low pow-
er consumption are needed. The LM7341 performance can
easily meet these requirements.
OPTICAL LINE ISOLATION FOR MODEMS
The combination of the low distortion and good load driving
capabilities of the LM7341 make it an excellent choice for
driving opto-coupler circuits to achieve line isolation for
modems. This technique prevents telephone line noise from
coupling onto the modem signal. Superior isolation is
achieved by coupling the signal optically from the computer
modem to the telephone lines; however, this also requires a
low distortion at relatively high currents. Due to its low distor-
tion at high output drive currents, the LM7341 fulfills this need,
in this and in other telecom applications.
20206054
FIGURE 1. Inverting Comparator
Similarly a non-inverting comparator at VS = 30V and 1V of
overdrive there is typically 12 µs of propagation delay. At
VS = 30V and 50 mV of overdrive there is typically 17 μs of
propagation delay.
REMOTE MICROPHONE IN PERSONAL COMPUTERS
Remote microphones in Personal Computers often utilize a
microphone at the top of the monitor which must drive a long
cable in a high noise environment. One method often used to
reduce the nose is to lower the signal impedance, which re-
duces the noise pickup. In this configuration, the amplifier
usually requires 30 dB–40 dB of gain, at bandwidths higher
than most low-power CMOS parts can achieve. The LM7341
offers the tiny package, higher bandwidths, and greater out-
put drive capability than other rail-to-rail input/output parts can
provide for this application.
20206055
LM7341 AS A COMPARATOR
FIGURE 2. Non-Inverting Comparator
The LM7341 can also be used as a comparator and provides
quite reasonable performance. Note however that unlike a
typical comparator an op amp has a maximum allowed dif-
ferential voltage between the input pins. For the LM7341, as
stated in the Absolute Maximum Ratings section, this maxi-
mum voltage is VIN Differential = ±15V. Beyond this limit, even
for a short time, damage to the device may occur.
COMPARATOR WITH HYSTERESIS
The basic comparator configuration may oscillate or produce
a noisy output if the applied differential input voltage is near
the comparator's offset voltage. This usually happens when
the input signal is moving very slowly across the comparator's
switching threshold. This problem can be prevented by the
addition of hysteresis or positive feedback.
As an inverting comparator at VS = 30V and 1V of overdrive
there is typically 12 μs of propagation delay. At VS = 30V and
50 mV of overdrive there is typically 17 µs of propagation de-
lay.

INVERTING COMPARATOR WITH HYSTERESIS
sistors can be presented as R2||R3 in series with R1. The
upper trip voltage VA2 is defined as
The inverting comparator with hysteresis requires a three re-
sistor network that is referenced to the supply voltage VCC of
the comparator, as shown in Figure 3. When VIN at the in-
verting input is less than VA, the voltage at the non-inverting
node of the comparator (VIN < VA), the output voltage is high
(for simplicity assume VOUT switches as high as VCC). The
three network resistors can be represented as R1||R3 in series
with R2. The lower input trip voltage VA1 is defined as
VA2 = VCC (R2||R3) / ((R1+ (R2||R3)
The total hysteresis provided by the network is defined as
Delta VA = VA1- VA2
For example to achieve 50 mV of hysteresis when VCC = 30V
set R1 = 4.02 kΩ, R2 = 4.02 kΩ, and R3 = 1.21 MΩ. With these
resistors selected the error due to input bias current is ap-
proximately 1 mV. To minimize this error it is best to use low
resistor values on the inputs.
VA1 = VCCR2 / ((R1||R3) + R2)
When VIN is greater than VA (VIN > VA), the output voltage is
low, very close to ground. In this case the three network re-

NON-INVERTING COMPARATOR WITH HYSTERESIS
VIN2 = (VREF (R1+ R2) - VCCR1)/R2
A non-inverting comparator with hysteresis requires a two re-
sistor network, and a voltage reference (VREF) at the inverting
input. When VIN is low, the output is also low. For the output
to switch from low to high, VIN must rise up to VIN1 where
VIN1 is calculated by
The hysteresis of this circuit is the difference between VIN1
and VIN2
.
Delta VIN = VCCR1/R2
For example to achieve 50 mV of hysteresis when VCC = 30V
set R1 = 20Ω and R2 = 12.1 kΩ.
VIN1 = R1*(VREF/R2) + VREF
When VIN is high, the output is also high, to make the com-
parator switch back to it's low state, VIN must equal VREF
before VA will again equal VREF . VIN can be calculated by
