The LMC6482 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
It is ideal for systems, such as data acquisition, that
require a large input signal range. The LMC6482 is
also an excellent upgrade for circuits using limited
common-mode range amplifiers such as the TLC272
Maximum dynamic signal range is assured in low
voltage and single supply systems by the LMC6482's
rail-to-rail output swing. The LMC6482's rail-to-rail
output swing is ensured for loads down to 600Ω.
Ensured low voltage characteristics and low power
dissipation make the LMC6482 especially well-suited
for battery-operated systems.
See the LMC6484 data sheet for a Quad CMOS
operational amplifier with these same features.
