Precision CMOS Dual Micropower Operational Amplifier
LMC6062 Precision CMOS Dual Micropower Operational Amplifier
November 1994
General Description
The LMC6062 is a precision dual low offset voltage, micropower 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 includes ground. Thesefeatures, plus its low power consumption, 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.
