1 / 10 page LF347, LF347B JFET-INPUT QUAD OPERATIONAL AMPLIFIERS SLOS013B – MARCH 1987 – REVISED AUGUST 1994 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Low Input Bias Current...50 pA Typ D Low Input Noise Current 0.01 pA/ √Hz Typ D Low Total Harmonic Distortion D Low Supply Current... 8 mA Typ D Gain Bandwidth...3 MHz Typ D High Slew Rate...13 V/µs Typ D Pin Compatible With the LM348 description These devices are low-cost, high-speed, JFET-input operational amplifiers. They require low supply current yet maintain a large gain-bandwidth product and a fast slew rate. In addition, their matched high-voltage JFET inputs provide very low input bias and offset current. The LF347 and LF347B can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits. The LF347 and LF347B are characterized for operation from 0 °C to 70°C. symbol (each amplifier) – + IN – IN + OUT AVAILABLE OPTIONS VIOmax PACKAGE TA VIOmax AT 25 °C SMALL OUTLINE (D) PLASTIC DIP (N) 0 °Cto70°C 10 mV LF347D LF347N 0 °C to 70°C 5 mV LF347BD LF347BN The D packages are available taped and reeled.
