LT1991 Overview
The LT®1991 bines a precision operational amplifier with eight precision resistors to form a one-chip solution for accurately amplifying voltages. Gains from 13 to 14 with a gain accuracy of 0.04% can be achieved using no external ponents. The device is particularly well suited for use as a difference amplifier, where the excellent resistor matching results in a mon mode rejection ratio of greater than 75dB.
