DESCRIPTION

The INA2141 is a low power, dual 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 INA2141 is laser trimmed for very low offset

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

rejection (117dB at G = 100). It operates with

power supplies as low as ±2.25V, and quiescent current

is only 750mA per amplifier—ideal for battery

operated systems.

Packages are 16-pin plastic DIP, and SOL-16

surface-mount, specified for the –40°C to +85°C

temperature range.
