Wide-bandwidth JFET-input quad operational amplifier

 

Description

The LF347 and LF347B devices are low-cost, high-speed, JFET-input operational amplifiers. They require low supply current yet maintain a large gain-bandwidth product and a fast slew rate. In addition, their matched high-voltage JFET inputs provide very low input bias and offset current.

The LF347 and LF347B can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits.

The LF347 and LF347B devices are characterized for operation from 0°C to 70°C.

Features

  • Low Input Bias Current: 50 pA Typical
  • Low Input Noise Current: 0.01 pA/√Hz Typical
  • Low Total Harmonic Distortion
  • Low Supply Current: 8 mA Typical
  • Gain Bandwidth: 3 MHz Typical
  • High Slew Rate: 13 V/ms Typical
