LTC6090HFE#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6090HFE#TRPBF is a high-voltage, precision monolithic operational amplifier from Analog Devices. It features a rail-to-rail output stage and picoamp input bias current, designed for unity gain stability. The device operates on supply voltages ranging from ±4.75V to ±70V (140V total). Key electrical specifications include a maximum input offset voltage of ±1250µV, a typical slew rate of 21V/µs, and a gain-bandwidth product of 12MHz. It provides a minimum common-mode rejection ratio of 130dB and includes thermal shutdown protection with a TFLAG output.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the H-suffix corresponds to the extended operating junction temperature range of –40°C to 125°C. Ensure compatibility with the 16-lead TSSOP package dimensions and exposed pad soldering requirements during procurement planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the LTC6090HFE#TRPBF for applications requiring high voltage buffering or high gain configurations with minimal input leakage. The H-suffix ensures performance across the full industrial temperature range. Consider the 16-lead TSSOP package for its guard pins which facilitate low-leakage PCB layouts. Verify that the load capacitance does not exceed the specified limits to maintain stability.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the LTC6090 family of high-voltage CMOS operational amplifiers manufactured by Analog Devices. The family includes variants such as the LTC6090-5, which is stable only in noise gain configurations of 5 or greater. The HFE variant specifically denotes the high-temperature grade housed in a 16-lead plastic TSSOP package with an exposed pad for thermal management.
