LT1996CMS#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1996CMS#TRPBF is a precision, micropower gain-selectable amplifier from Analog Devices Inc. It integrates an operational amplifier with eight matched resistors to form a one-chip solution for voltage amplification without external components. The device supports difference, inverting, and noninverting configurations with gains ranging from -117 to 118. It features a maximum input offset voltage of 50µV, a gain bandwidth product of 560kHz, and rail-to-rail output capability. Operating on a single supply from 2.7V to 36V or split supplies up to ±18V, it draws only 100µA at 5V. The component is housed in a space-saving 10-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix CMS indicates the commercial temperature grade and MSOP package configuration. Confirm that the TRPBF designation corresponds to the tape and reel packaging format required for automated assembly processes. Ensure compatibility with the intended operating temperature range of –40°C to 85°C for the specified grade.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when board space is limited and multiple gain configurations are needed without adding discrete resistors. It is suitable for applications requiring high common mode rejection and low power consumption. Consider the finite set of available gains and the input impedance characteristics relative to the source resistance for optimal accuracy.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1996 family of precision gain-selectable amplifiers. It combines a precision operational amplifier with internal SiChrome-based matched resistors. The series is designed to simplify signal conditioning by providing multiple classical amplifier topologies in a single integrated circuit, reducing component count and potential mismatch errors associated with discrete resistor networks.
