LF347, LF347B

SLOS013C –MARCH 1987–REVISED MARCH 2016
LF347, LF347B JFET-Input Quad Operational Amplifiers 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 Applications Motor Integrated Systems: UPS Drives and Control Solutions: AC Inverters and VF
Drives Renewables: Solar Inverters Pro Audio Mixers Oscilloscopes Description
The LF347 and LF347B devices are low-cost, high-
speed, JFET-input operational amplifiers. They
require low supply current yet maintaina large gain-
bandwidth product anda 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 usedin 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°Cto 70°C.
