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 this device unique among
rail-to-rail input ampliers. The device is an excellent
choice 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 ampliers, such as the TLC272
and TLC277.
Maximum dynamic signal range is provided in low
voltage and single supply systems by the rail-to-rail
output swing of the LMC6482. The rail-to-rail output
swing is maintained for loads down to 600 of theΩ
device. Specied low-voltage characteristics and low-
power dissipation make the LMC6482 a great choice
for battery-operated systems.
The LMC6482 is available in 8-pin PDIP and SOIC
packages. The device is also available in a VSSOP
package, almost half the size of a SOIC-8 device.

amplier with these same features.
