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-effec- tive 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 SOIC packages. Performance grades include com- mercial and industrial temperature ranges.

ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degrada- tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ABSOLUTE MAXIMUM RATINGS NOTE: (1) Short-circuit to ground, one amplifier per package.
