Micropower op amps work down to 1.8V total supply, guaranteed over temperature

Glen Brisebois

Abstract

The LT6000 and LT6003 family of op amps, which offer 13μA and 1μA micropower operation over a wide supply range from 18V all the way down to 1.8V, guaranteed over temperature, are described.

Introduction

Micropower op amps extend the run time of battery-powered systems and reduce energy consumption in other energy limited systems. Nevertheless, battery voltages change as they are depleted. To maximize a system’s run time, op amps should operate over a wide enough supply range to make use of the complete range of battery voltages, from fully charged to fully depleted. The new ...
