INA151 Precision Difference Amplifiers

Texas Instruments INA151 Precision Difference Amplifiers come with an input common-mode voltage range of up to 110V above the negative supply (recommended). These amplifiers feature a 125dB minimum high common-mode rejection ratio, >1.4MΩ common-mode input impedance, and an offset-voltage drift of 0.6μV/ºC for 1V/V gain. The INA151 precision difference amplifiers are available with gains of 1V/V (INA151A), 2/3V/V (INA151B), 1/2V/V (INA151C), and 1/4V/V (INA151D). These amplifiers include an Enable/disable (EN) pin that provides a high-impedance output, allowing stacking multiple INA151s on the outputs. The INA151 precision difference amplifiers are available in a standard 8-pin package and a -40°C to 125°C specified temperature range. Typical applications include analog input module, mixed module (AI, AO, DI, and DO), precision multifunction input output DAQ, and battery cell formation, and test equipment.
