Another design for a DI box, based on a low-voltage rail-to-rail MAXIM
opamp MAX4167. They do require +- 1.35V. Would they work from +-
1.2V? I'd like to run off of 2 AAA rechargables.
Using 2 cells I can have a symmetrical supply. This significantly
simplifies the circuit to the point of triviality, as no coupling caps
I used a small perfboard with a plastic socket. One of the channels
works, the other one doesn't. All connections seem to check out fine,
socket is fine too. Something's wrong that I don't see. EDIT: was
just a bad solder joint.
