LMC6062
Precision CMOS Dual Micropower Operational Amplifier
General Description
The LMC6062 is a precision dual low offset voltage, mi-
cropower operational amplifier, capable of precision 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 in-
cludes ground. These features, plus its low power consump-
tion, make the LMC6062 ideally suited for battery powered
applications.
Other applications using the LMC6062 include precision
full-wave rectifiers, integrators, references, sample-and-hold
circuits, and true instrumentation amplifiers.
This device is built with National’s advanced double-Poly
Silicon-Gate CMOS process.
For designs that require higher speed, see the LMC6082
precision dual operational amplifier.
