DescriptionThe LMC6081 is a precision low offset voltage operational amplifier, 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 its low offset voltage, make the LMC6081 ideally suited for precision circuit applications.
Other applications using the LMC6081 include precision full-wave rectifiers, integrators, references, and sample-and-hold circuits.
This device is built with National's advanced Double-Poly Silicon-Gate CMOS process.
For designs with more critical power demands, see the LMC6061 precision micropower operational amplifier.
For a dual or quad operational amplifier with similar features, see the LMC6082 or LMC6084 respectively.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
