说明

The LMC6082 is a precision dual 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 LMC6082 ideally suited for precision circuit applications.

Other applications using the LMC6082 include precision full-wave rectifiers, integrators, references, and sample-and-hold circuits.

This device is built with TI's advanced Double-Poly Silicon-Gate CMOS process.
