LMC6081
Precision CMOS Single Operational Amplifier
General Description
The LMC6081 is a precision low offset voltage operational
amplifier, capable of single supply operation. Performance
characteristics include ultra low input bias current, high volt-
age 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.
