LF347 quad op amp in a 14-pin DIP package. The LF347 is a low cost, high speed quad JFET input operational amplifier with an internally trimmed input offset voltage ( BI-FET II™ technology). The device requires a low supply current and yet maintains a large gain bandwidth product and a fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF347 is pin compatible with the standard LM348. This feature allows designers to immediately upgrade the overall performance of existing LF348 and LM324 designs.

The LF347 may be used in applications such as high speed integrators, fast D/A converters, sample-and-hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth. The device has low noise and offset voltage drift.

Features:

  • Internally Trimmed Offset Voltage: 10 mV max
  • Low Input Bias Current: 50 pA
  • Low Input Noise Current: 0.01 pA/√Hz
  • Wide Gain Bandwidth: 4 MHz
  • High Slew Rate: 13 V/μs
  • Low Supply Current: 7.2 mA
  • High Input Impedance:1012Ω
