Texas Instruments  INA141U/2K5

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 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.
