Product Introduction

Overview

The LTC1992CMS8#TRPBF is a part of the LTC1992 family of low power, fully differential input/output amplifiers produced by Analog Devices Inc. This family consists of five fully differential amplifiers, including the LTC1992-1, LTC1992-2, LTC1992-5, and LTC1992-10, which are fixed gain blocks with gains of 1, 2, 5, and 10 respectively. The LTC1992 is an unconstrained fully differential amplifier, designed for precision and stability in various signal processing applications.

These amplifiers are known for their low power consumption, rail-to-rail input and output capabilities, and a separate internal common mode feedback path that ensures outstanding output phase balancing and reduced second-order harmonics. The VOCM pin allows for easy level shifting of signals by setting the output common mode level independently of the input common mode level.
