LMC6484AIMX/NOPB

The LMC6482 and LMC6484 (LMC648x) devices
provide 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 these devices unique among rail-to-rail input
amplifiers. The devices are an excellent choice for
systems that require a large input signal range,
such as data acquisition. The LMC648x are also an
excellent upgrade for circuits using limited commonmode range amplifiers, such as the TLC272, TLC274,
TLC277 and TLC279.
Maximum dynamic signal range is provided in low
voltage and single supply systems by the rail-to-rail
output swing of the LMC648x. The rail-to-rail output
swing is maintained for loads down to 600Ω of the
device. Specified low-voltage characteristics and lowpower dissipation make the LMC648x a great choice
for battery-operated systems.
The LMC648x devices are available in PDIP, SOIC,
and VSSOP packages.
