1 / 10 page LF412C DUAL JFET INPUT OPERATIONAL AMPLIFIER SLOS010B − MARCH 1987 − REVISED AUGUST 1994 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 D Low Input Bias Current...50 pA Typ D Low Input Noise Current 0.01 pA/ √Hz Typ D Low Supply Current . . . 4.5 mA Typ D High Input impedance ...1012 Ω Typ D Internally Trimmed Offset Voltage D Wide Gain Bandwidth ...3 MHz Typ D High Slew Rate . . . 13 V/µs Typ description This device is a low-cost, high-speed, JFET-input operational amplifier with very low input offset voltage and a specified maximum input offset voltage drift. 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 LF412C can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits. The LF412C is characterized for operation from 0 °C to 70°C. symbol (each amplifier) IN − OUT IN + AVAILABLE OPTIONS VIOmax PACKAGE TA VIOmax AT 25 °C SMALL OUTLINE (D) PLASTIC DIP (P) 0 °C to 70°C 3 mV LF412CD LF412CP The D packages are available taped and reeled.
