LMC6082
Precision CMOS Dual Operational Amplifier
General Description
The LMC6082 is a precision dual low offset voltage opera-
tional amplifier, capable of single supply operation. Perfor-
mance 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 National’s advanced Double-Poly
Silicon-Gate CMOS process.
For designs with more critical power demands, see the
LMC6062 precision dual micropower operational amplifier.
