    This is an op amp circuit from the datasheet of OPA567 (top of page 19 of the datasheet). I was wondering if it is possible to modify this circuit such that it uses positive supply instead of negative, and sources current instead of sinking it.

    Thanks.

    Hello,

    You can post the circuit directly here.
    A sharing site is not so well done over here.
    A lot of people do not trust files from there.

    You can attach a file with the "manage attachments" a litthe bit down the page.

    Greetings,
    Bertus

    Absolutely. In fact the 567 is designed primarily to work with a single positive supply. Like just about any op amp the choice of ground reference is pretty arbitrary. Just be sure to modify ALL your ground points to reflect this!

    Thanks.

    Apart from changing positive supply to using +5V and negative supply to using ground, is there any other modification which I should make for the circuit to work as a current source?

    Sorry but I'm fairly new to doing circuits.
