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. It uses the same offset voltage adjustment circuits as the 741. The LF351 can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits. The LF351 is characterized for operation from 0C to 70C. symbol (each amplifier) IN - IN + BAL1 BAL2 2 - 3 6 + OUT 1 5 AVAILABLE OPTIONS TA VIOmax AT 25C 0C to 70C 10 mV PACKAGE SMALL OUTLINE (D) PLASTIC DIP (P) LF351D LF351P The D packages are available taped and reeled.
