Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: BOB-09816. This is an older version of the Op Amp breakout board, shown here for historical purposes. The new version uses a surface mount potentiometer for gain adjustments instead of the larger, through-hole component.

Description: This is a simple Op Amp breakout board, set up as a 2-stage amplifier with a gain of 100 (gain of 10 for each stage). The on-board trim pot sets the signal level between the stages, not the feedback path. The bandwidth is set to 15.9kHz by a pair of feedback capacitors, or over 100kHz with the caps removed. The LMV358 opamp can source up to 160mA and works well as a low impedance driver/buffer.

  • Oops! There is a 10k on the input. Additionally, jumper C5 and C6 to work woth DC.

  • Jumper that input cap so it will work with DC; maybe a solder pad jumper. I’d like to see a neg voltage on the op-amp so it could be used for null or used for offsetting the input. Maybe a current limiting res on the input too. Thanks.

    • Could you explain this for me? How do I make this work with DC? I ‘bridge’ or jumper the input terminal….but connect it to what exactly? Thanks

  • @ aws
    I’m a noob, how can you tell from the schematic that it is AC?

  • Note that it only passes AC signals (see schematic)

  • The 3 thru-holes visible on the bottom right of the board appear to be for the pot (schematic R7).

  • what do the pins on the bottom go to?
