LTC6363 Low Power Differential Amplifiers Analog Devices LTC6363 Low Power Differential Amplifiers are designed with rail-to-rail outputs optimised to drive successive approximation register (SAR) ADCs. These LTC6363 differential amplifiers feature 2mA maximum supply current, low distortion, 94dB minimum CMRR, fast settling, 100µV maximum offset voltage, and low power shutdown. The LTC6363 are stand-alone differential amplifiers that use four external resistors to set the gain.
