Overview
The LMC6482AIMX/NOPB is a CMOS dual rail-to-rail input/output operational amplifier manufactured by Texas Instruments. This device features two independent, high-performance operational amplifiers with wide bandwidths, wide supply voltage ranges, and low power operation. The LMC6482AIMX/NOPB is designed for applications requiring a large input signal range and is particularly suited for systems such as data acquisition, medical instrumentation, and industrial instrumentation. It is an excellent upgrade for circuits using limited common-mode range amplifiers like the TLC272 and TLC277.
