The LTC6363 family includes four fully differential, low power, low noise amplifiers with rail-to-rail outputs optimized to drive SAR ADCs. The LTC6363 is a stand-alone differential amplifier whose gain is typically set using four external resistors. The LTC6363-0.5, LTC6363-1 and LTC6363-2 all have internal termination resistors to create fixed gain blocks with gains of 0.5V/V, 1V/V and 2V/V respectively. Each fixed-gain amplifier features precision laser-trimmed on-chip resistors for precise, ultra-stable gain and excellent CMRR performance.
