DescriptionThe 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.
