3 Description
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.
