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 amplifiers 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
output swing. The LMC6482's rail-to-rail output swing is ensured for loads down to 600Ω.
Ensured low voltage characteristics and low power dissipation make the LMC6482 especially well-suited for
battery-operated systems.
LMC6482 is also available in 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.
