3 Description
The LMC6482 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. The device 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 and TLC277.
Maximum dynamic signal range is assured in low
voltage and single supply systems by the rail-to-rail
output swing of the LMC6482. The rail-to-rail output
swing is ensured for loads down to 600 Ω of the
device. Ensured low-voltage characteristics and low-
power dissipation make the LMC6482 especially well-
suited for battery-operated systems. LMC6482 is also
available in a VSSOP package, which is almost half
the size of a SOIC-8 device. See the LMC6484 data
sheet for a quad CMOS operational amplifier with
these same features.
