This LF353 device is a low-cost, high-speed, JFET input operational amplifier with very low input offset voltage. It requires low supply current yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset currents. The LF353 can be used in applications such as high speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits. The LF353 is characterized for operation from 0°C to 70°C.
