说明

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 options.

The OPA131 series offers excellent general-purpose performance, 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 industrial temperature ranges.
