LMC6484 - National Semiconductor

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

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 u.
