LF411 - Low Offset/ Low Drift JFET Input Operational Amplifier

Description

These devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and guaranteed input offset voltage drift.

They require low supply current yet maintain a large gain bandwidth product and fast slew rate.

Features

  • Internally trimmed offset voltage: 0.5 mV(max) Input offset voltage drift: 10 µV/˚C(max) Low input bias current: 50 pA Low input noise current: Wide gain bandwidth: 3 MHz(min) High slew rate: 10V/µs(min) Low supply current: 1.8 mA High input impedance: 1012Ω Low total harmonic distortion AV = 10, RL = 10k, VO = 20 Vp-p, BW = 20 Hz.

LF411 Low Offset, Low Drift JFET Input Operational Amplifier April 1998 LF411 Low Offset, Low Drift JFET Input Operational Amplifier General Description These devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and guaranteed input offset voltage drift. They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF411 is pin compatible with the standard LM741 allowing designers to immediately upgrade the overall performance of existing designs.
