Product Summary
The INA2141U 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 INA2141U is laser trimmed for very low offset voltage (50mV), drift (0.5mV/℃)and high commonmode rejection (117dB at G = 100). The INA2141U 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℃ to +85℃ temperature range.
