Low power differential amplifiers use four external resistors to set the gain

Analog Devices LTC6363 Low Power Differential Amplifiers are created with rail-to-rail outputs optimised to drive consecutive approximation register (SAR) ADCs. These differential amplifiers highlights include 2mA maximum supply current, 94dB minimum CMRR, low distortion, 100µV maximum offset voltage, fast settling, and low power shutdown. The devices are stand-alone differential amplifiers that utilise four external resistors to set the gain. These differential amplifiers are also offered in fixed gain blocks with 0.5V/V, 1V/V and 2V/V gains utilising internal matched resistors. These fixed gain differential amplifiers comprise of precision laser trimmed on-chip resistors for ultrastable gain, accuracy, and excellent CMRR. Typical applications comprise low power level shifter, ADC drivers, battery-powered instrumentation, differential line drivers, and 20-bit/18-bit/16-bit SAR ADC drivers.
