Description for the LMC6482
The LMC6482 and LMC6484 (LMC648x) devices provide 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 these devices unique among rail-to-rail input amplifiers. The devices are an excellent choice for systems that require a large input signal range, such as data acquisition. The LMC648x are also an excellent upgrade for circuits using limited common-mode range amplifiers, such as the TLC272, TLC274, TLC277 and TLC279.
Maximum dynamic signal range is provided in low voltage and single supply systems by the rail-to-rail output swing of the LMC648x. The rail-to-rail output swing is maintained for loads down to 600Ω of the device. Specified low-voltage characteristics and low-power dissipation make the LMC648x a great choice for battery-operated systems.
The LMC648x devices are available in PDIP, SOIC, and VSSOP packages.
