Overview
The LF353P, produced by Texas Instruments, is a low-cost, high-speed, JFET-input dual operational amplifier. It is characterized by its very low input offset voltage, low input bias and offset currents, and high input impedance. This device is suitable for a wide range of applications due to its large gain-bandwidth product and fast slew rate. The LF353P operates from a supply voltage range of 3.5V to 18V and is designed for operation over a temperature range of 0°C to 70°C.
