Hi Team,
My customer considers shut down sequence as the following for TPA2026D2.
----------------------------------------
write 0x03 (01H register) : disabling right and left amplifiers
write 0x23 (01H register) : SWS=1
wait 80us
apply SDZ high to Low
----------------------------------------
Is wait time 80us above sufficient?
The background of the question is datasheet shows "Do not interrupt the shutdown sequence after changing SWS from 0 to 1." so would like to confirm it.
Does figure 29 shows wait time more than 1.6ms is required?
Best Regards,
Yaita
