DESCRIPTION
The INA141 is a low power, general purpose instru-
mentation amplifier offering excellent accuracy. Its
versatile 3-op amp design and small size make it ideal
for a wide range of applications. Current-feedback
input circuitry provides wide bandwidth even at high
gain (200kHz at G = 100).
Simple pin connections set an accurate gain of 10 or
100V/V without external resistors. Internal input pro-
tection can withstand up to ±40V without damage.
The INA141 is laser trimmed for very low offset
voltage (50µV), drift (0.5µV/°C) and high common-
mode rejection (117dB at G = 100). It operates with
power supplies as low as ±2.25V, and quiescent
current is only 750µA—ideal for battery operated
systems.
The INA141 is available in 8-pin plastic DIP, and
SO-8 surface-mount packages, specified for the –40°C
to +85°C temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
