DESCRIPTION

The LT?6372-1 is a gain programmable, high precision instrumentation amplifier that delivers industry leading DC precision. This high precision enables smaller signals to be sensed and eases calibration requirements, particularly over temperature. The LT6372-1 incorporates features into the LT6370 which further improve accuracy and simplify interfacing to an ADC.
