LMC6084

Precision CMOS Quad Operational Amplifier

General Description

The LMC6084 is a precision quad 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

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 fea-

tures, see the LMC6081 or LMC6082 respectively.
