Hello,
I'm designing a 70W x 3 hifi AVR product for a client.
We are looking at using the TAS5631B part in a hifi AVR product. The AVR will have user accessible terminals in the back of the amp. The TAS part seems to check for output shorts to ground on startup but not afterwards. We are concerned that a user may leave the amp on while connecting a speaker and may accidentally short an output to chassis ground (since the outputs are sitting at half supply). From the datasheet it seems that this would break the part. Please help us confirm/deny this. If it would indeed break the part, can you recommend how best to use this part for an AVR product? Is there an app note to reference or a better part to use?
Thanks,
