Description

General part information

OPA2131 Series

The OPAx131 series of FET-input op amps provides high performance at low cost. The OPA131 single, OPA2131 dual, and OPA4131 quad versions in industry-standard pinouts allow cost-effective design options.

The OPAx131 series offers excellent general-purpose performance, including low offset voltage, drift, and good dynamic characteristics.

Single and dual versions are available in an 8-pin, SOIC, surface-mount package. The quad version is available in 14-pin and 16-pin, SOIC, surface-mount packages, and a 14-pin PDIP package.
