DESCRIPTION

The OPA131 series of FET-input op amps provides high

performance at low cost. Single, dual, and quad versions in

industry-standard pinouts allow cost-effective design op-

tions.

The OPA131 series offers excellent general-purpose perfor-

mance, including low offset voltage, drift, and good dynamic

characteristics.

Single, dual, and quad versions are available in DIP and SO

packages. Performance grades include commercial and in-

dustrial temperature ranges.
