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 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 rail-to-rail
output swing of the LMC6484. The rail-to-rail output
swing of the LMC6484 is ensured for loads down to
600 Ω.
Specified low voltage characteristics and low power
dissipation make the LMC6484 especially well-suited
for battery-operated systems.
See the LMC6482 (SNOS674) data sheet for a dual
CMOS operational amplifier with these same
features.
