LMC6061
Precision CMOS Single Micropower Operational
Amplifier
General Description
The LMC6061 is a precision single 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.These features, plus its low power consumption, make the LMC6061 ideally suited for battery powered
applications.
Other applications using the LMC6061 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 LMC6081
precision single operational amplifier.
For a dual or quad operational amplifier with similar features,
see the LMC6062 or LMC6064 respectively.
