HI,
I've been reading the posts about the turn on sequence for the TAS5630 and have a question.
Can I use the ENABLE pin on the OPA1632 as a mute during the power up sequence? The OPA1632 has a +12 volt supply and VCOM open.
1) Connect the audio source to the inputs with the audio source stopped.
2) Apply VDD, GVDD and PVDD.
3) Release /RESET
4) Wait for READY high.
5) Apply audio.
I'm worried that if the outputs of the OPA1632 go to ground when ENABLE is low, that when ENABLE goes high that TAS5630 input coupling capacitors will overdrive the inputs to 6 volts momentarily and damage the TAS5630.
Or am I lucky and the outputs go to VCOM?
Thank you,
Lowell
