My TDA7293 project... please help
I need your help again guys. I am designing a pcb for the TDA7293 chipamp and I have a few questions so far.... (I don't want to end up burning the chip)
In the schematic,
1. What is the working voltage of C5 (22uf Bootstrap Capacitor)
2. How do I implement the use pin 5 (Clip Detect)?
Planned psu is +/-50V @ 10A.
Thank you in advance!

Take a look at this document (in German, but the circuit and PCB details might be very helpfulk):
A100 TDA7293 amp
According to this, and the parts description on Schuro.de, you should use a 25V - 63V cap for C5 (C7 in the A100 circuit).
I cannot help you with clipping detection, since the designer of the A100 chose to omit it...
Hope this helps,
