The LMC6081, LMC6082, and LMC6084 (LMC608x) are precision, low-offset-voltage operational amplifiers (op amps), capable of single supply operation. Performance characteristics include ultra low input bias current, high voltage gain, rail-to-rail output swing, and an input common-mode voltage range that includes ground. These features, plus the low offset voltage, make the LMC608x an excellent choice for precision circuit applications.

Other applications using the LMC608x include precision full-wave rectifiers, integrators, references, and sample-and-hold circuits.

For designs with more critical power demands, see the LMC6062 precision, dual, micropower operational amplifier.
