PI differential integrator power question

[6666]

Hello all does your typical PI differential integrator have to always be powered with + and - 5 volts for it to work properly, or can you also power it for just ground and +5 volts, thanks.

If the preamp is +/-5v, then that's the easy way to do it. But you could offset the signal and run the integrator on +5 only.

Thanks Carl, I am trying a couple of ideas for a micro based +5 volt PI,
Actually I am trying +5 volt on the preamp to, so if both the preamp and the integrator are at +5 volt would it still work ?

If I remember correctly, the TD3X used a single supply (Ground and +8V). Check out its schematic. You can see the offset adjust required prior to the integrator.

I will have a look thanks

The PI circuits in ITMD run on 9v, they would easily run on 5v. The coil is cap-coupled to the preamp and a rail splitter provides "analog ground."
