10 Pack LF347 IC JFET-Input Quad Operational Amplifier, 14 Pin DIPThe 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
