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. The LMC6484's rail-to-rail output swing is ensured for loads down to 600Ω.
Ensured low voltage characteristics and low power dissipation make the LMC6484 especially well-suited for battery-operated systems.
See the LMC6482 data sheet for a Dual CMOS operational amplifier with these same features.
