3 Description
The LMC6482-MIL 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-MIL 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-MIL. 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-MIL
especially well-suited for battery-operated systems.
LMC6482-MIL 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.
