OPA131 (ACTIVE) General Purpose FET-Input Operational Amplifiers

 

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 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.

Features

  • FET INPUT: IB = 50pA max
  • LOW OFFSET VOLTAGE: 750uV max
  • WIDE SUPPLY RANGE: ±4.5V to ±18V
  • SLEW RATE: 10V/us
  • WIDE BANDWIDTH: 4MHz
  • EXCELLENT CAPACITIVE LOAD DRIVE
  • SINGLE, DUAL, QUAD VERSIONS
