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.
