The 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 TI'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.
