SLOS013C – MARCH 1987 – REVISED MARCH 2016 LF347, LF347B JFET-Input Quad Operational Amplifiers
1 Features 3 Description The LF347 and LF347B devices are low-cost, highspeed, JFET-input operational amplifiers. They
require low supply current yet maintain a large gainbandwidth product and a fast slew rate. In addition,
their matched high-voltage JFET inputs provide very
low input bias and offset current. 1 Low Input Bias Current: 50 pA Typical
Low Input Noise Current: 0.01 pA/в€љHz Typical
Low Total Harmonic Distortion
Low Supply Current: 8 mA Typical
Gain Bandwidth: 3 MHz Typical
High Slew Rate: 13 V/ms Typical 2 Applications Motor Integrated Systems: UPS
Drives and Control Solutions: AC Inverters and VF
Drives
Renewables: Solar Inverters
Pro Audio Mixers
Oscilloscopes 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 …
