LMC6484 - CMOS Quad Rail-to-Rail Input and Output Operational Amplifier

General Description

The LMC6484 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.

LMC6484 CMOS Quad Rail-to-Rail Input and Output Operational Amplifier May 1999 LMC6484 CMOS Quad Rail-to-Rail Input and Output Operational Amplifier General Description The LMC6484 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 LMC6484’s rail-to-rail output swing.
