LMC6482
CMOS Dual Rail-To-Rail Input and Output Operational
Amplifier
General Description
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 input amplifiers.
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 am-
plifiers such as the TLC272 and TLC277.
Maximum dynamic signal range is assured in low voltage
and single supply systems by the LMC6482’s rail-to-rail out-
put swing. The LMC6482’s rail-to-rail output swing is guar-
anteed for loads down to 600Ω.
Guaranteed low voltage characteristics and low power dis-
sipation make the LMC6482 especially well-suited for
battery-operated systems.
LMC6482 is also available in MSOP package which is al-
most half the size of a SO-8 device.
See the LMC6484 data sheet for a Quad CMOS operational
amplifier with these same features.
