LT6375HMS#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT6375HMS#TRPBF is a unity-gain difference amplifier featuring ±270V common mode voltage range and rail-to-rail output. It integrates a precision op amp with Over-The-Top protected inputs and a highly-matched thin film resistor network. The device supports selectable internal resistor divider ratios (7, 20, or 25) to optimize system performance for specific input ranges. Key electrical parameters include a maximum gain error of 0.0075%, 1ppm/°C gain drift, and supply current of 350µA active. It operates on a wide supply voltage range of 3.3V to 50V and is specified over the –40°C to 125°C temperature range in a 16-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the H-grade suffix indicates the extended temperature range of –40°C to 125°C. Confirm the #TRPBF suffix denotes tape and reel packaging for the MSOP16 variant. Ensure the application requires the specific ±270V common mode capability and unity gain configuration provided by this part number.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high common mode voltages up to ±270V are present alongside precision signal requirements. Choose the appropriate reference pin configuration to set the desired resistor divider ratio based on the trade-off between input range and noise performance. Verify that the 350µA supply current fits the power budget and that the MSOP16 package accommodates the PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT6375 family of difference amplifiers designed for high common mode voltage applications. It serves as a replacement for isolation circuits and discrete solutions requiring precise differential measurement.
