LMC6484
CMOS Quad Rail-to-Rail Input and Output Operational
Amplifier
General Description
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 am-
plifiers 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 out-
put swing. The LMC6484’s rail-to-rail output swing is guaran-
teed for loads down to 600 .
Guaranteed low voltage characteristics and low power dissi-
pation 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.
