Hi Northstar,

This is probably not the best forum to ask help only for schematics, but here is one proposal.

3884

Gain control: 0 - 2V (below 0.3V in mute mode)
You will need two voltage supplies, otherwise it is very similar to application examples presented in ISD4003 specification.

There is not too much that can go wrong. ;)
Will there be some PBP code later? I hope so.

BR,
