Hello Eva,

Care to share the name of that PIC?
Because I have heard of people trying to use Atmega 16 chips.
But PIC?
Is it dsPIC series or just a fast PIC with PWM outputs?

I used the datasheet circuit and found it didnt work for me.

After a lot of work I eventually found the 10uf on VCC was too small and replaced it with 47uf and got it working.

On my next design I upped the supply to +/-45 volts and the 2092 oscillated on top of the audio. Again the same capacitor was at fault and i upped it to 100uf.

The 2092 is fussy about decoupling.
