About this product

Overview

Product overview

  • High performance JFET input OP amp
  • 120 dB internal amplifier isolation
  • Great for audio circuits, D/A convertors and high speed sample and hold circuits
  • Quad version 14-pin DIL package

Low-cost high performance JFET input op-amp that will directly replace and out-perform the 741 in most applications. The device is low noise, has distortion figures of less than 0.02% over the audio band, high slew rate (13V/µs), high input impedance (1012Ω) and wide bandwidth. The 347, internal amplifier isolation is 120dB. Additionally, the accurately matched JFET inputs provide very low input bias and offset currents. It is most important that input voltages never go more negative than the negative supply voltage or the device will be destroyed. The ICs are ideal for audio circuits, as well as fast D/A convertors, high speed integrators and sample-and-hold circuits. The 347 is supplied in a 14-pin DIL package and is a quad version. Note that since the inputs are JFETs not MOSFETs no special handling is required.

what frequency range this amplifier work can i use this for 13.56 MHZ frequency

Asked by: vedme
This starts at 20hz so would not be suitable I am afraid.

The picture shows two chips, one with 8 pins and one with 16 pins, which one is it or do they do a dual amp as well as a quad?

Asked by: Purplewelshy
This is a 14 pin please see the pin outs online for LF347N if you are unsure if this is suitable.
