Dual General-Purpose JFET-input Operational Amplifier - LF353

LF353 (ACTIVE)

Dual General-Purpose JFET-input Operational Amplifier

 

Description

This LF353 device is a low-cost, high-speed, JFET-input operational amplifier with very low input offset voltage. It requires low supply current yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset currents.

The LF353 can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits.

The LF353 is 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 Supply Current 3.6 mA Typical
  • High Input Impedance 1012 Ω Typical
  • Internally-Trimmed Offset Voltage
  • Gain Bandwidth 3 MHz Typical
  • High Slew Rate 13 V/µs Typical
