The LF347 and LF347B 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 integrator, digital-to-analog converters, sample-and-hold circuits, and many other circuits. The LF347 and LF347B devices are characterized for operation from 0C to 70C.
