Texas Instruments LF347
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. 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.FEATURES
