LMC6084
Precision CMOS Quad Operational Amplifier
LMC6084 Precision CMOS Quad Operational Amplifier
November 1994
General Description
The LMC6084 is a precision quad low offset voltage operational amplifier, capable of single supply operation. Performance characteristics include ultra low input bias current,
high voltagegain, rail-to-rail output swing, and an input common mode voltage range that includes ground. These features, plus its low offset voltage, make the LMC6084 ideally
suited for precision circuit applications.
Other applications using the LMC6084 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
LMC6064 precision quad micropower operational amplifier.
For a single or dual operational amplifier with similar features, see the LMC6081 or LMC6082 respectively.
