DESCRIPTION
The LTC®6363 family consists of four fully differential,
low power, low noise amplifiers with rail-to-rail outputs
optimized to drive SAR ADCs. The LTC6363 is a standalone
differential amplifier, where the gain is typically set using
four external resistors. The LTC6363-0.5, LTC6363-1, and
LTC6363-2 each have internal matched resistors to create
fixed gain blocks with gains of 0.5V/V, 1V/V, and 2V/V
respectively. Each of the fixed-gain amplifiers features
precision laser trimmed on-chip resistors for accurate,
ultrastable gain and excellent CMRR.
