DESCRIPTION

The INA141 is a low power, general purpose instrumentation 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 protection can withstand up to ±40V without damage.

The INA141 is laser trimmed for very low offset

voltage (50μV), drift (0.5μV/°C) and high commonmode 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.
