description
These devices are low-cost, high-speed, JFET-input operational amplifiers. They require low supply current yet
maintain a large gain-bandwidth product and a 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 used in applications such as high-speed integrators, digital-to-analog
converters, sample-and-hold circuits, and many other circuits.
The LF347 and LF347B are characterized for operation from 0 C to 70 C.
