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 this device unique among rail-to-rail input amplifiers.
The LMC6484 is an excellent choice for systems, such as data acquisition, that require a large input signal range. The device is also an excellent upgrade for circuits using limited common-mode range amplifiers, such as the TLC274 and TLC279.
Maximum dynamic signal range is maintained 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 specified for loads down to 600 Ω.
Specified low voltage characteristics and low power dissipation make the LMC6484 an excellent choice for battery-operated systems.
See the LMC6482 for a dual CMOS operational amplifier with these same features.
