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 com-
mon mode voltage range that includes ground. These fea-
tures, plus its low offset voltage, make the LMC6082 ideally
suited for precision circuit applications.
Other applications using the LMC6082 include precision
full-wave
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.
