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.

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 devices are characterized for

operation from 0°C to 70°C.
