Product Introduction

Overview

The LMC6482IMX/NOPB is a dual low-power, very low noise, rail-to-rail input-and-output CMOS operational amplifier (Op Amp) manufactured by Texas Instruments. This device is part of the LMC648x series, which is known for its rail-to-rail performance, extending the common-mode range to both supply rails. This feature, combined with excellent accuracy due to a high Common-Mode Rejection Ratio (CMRR), makes the LMC6482 an excellent choice for systems requiring a large input signal range, such as data acquisition systems. It is also an excellent upgrade for circuits using limited common-mode range amplifiers like the TLC272 and TLC277.
