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. symbol (each amplifier – IN – OUT + IN + AVAILABLE OPTIONS TA VIOmax AT 25°C 0°C to 70°C 10 mV PACKAGE SMALL OUTLINE (D) PLASTIC DIP (P) LF353D LF353P The D packages are available taped and reeled.
