3 Description

The LMC6484 device provides a common-mode range that extends to both supply rails. This rail-to-rail performance combined with excellent accuracy, due to a high CMRR, makes it unique among rail-to-rail input amplifiers.

It is ideal for systems, such as data acquisition, that require a large input signal range. The LMC6484 is also an excellent upgrade for circuits using limited common-mode range amplifiers such as the TLC274 and TLC279.

Maximum dynamic signal range is assured in low voltage and single-supply systems by the rail-to-rail output swing of the LMC6484. The rail-to-rail output swing of the LMC6484 is ensured for loads down to 600 Ω.

Specified low voltage characteristics and low power dissipation make the LMC6484 especially well-suited for battery-operated systems.

See the LMC6482 (SNOS674) data sheet for a dual CMOS operational amplifier with these same features.
