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.
