Other Parts Discussed in Thread: TAS5611A,
Hi,
A customer using TAS5611A asks us about the PVDD and GND pins of TPA3251.
Some PVDD and GND pin of TAS5611A have subscript to show uses (e.g. channel), while the PVDD pin name of TPA3251 are distinguished between AB and CD channels.
But the GND pin name of TPA3251 does not distinguish its uses.
As to GND:
Q1. Is #13 of TPA3251 a analog ground pin like #8 of TAS5611A?
Q2. Are #41 and #42 of TPA3251 ground pins only for A-channel like #48 and #49 of TAS5611A?
Q3. Is #34 of TPA3251 a ground pin only for B-channel like #46 and #47 of TAS5611A?
Q4. Is #33 of TPA3251 a ground pin only for C-channel like #34 and #35 of TAS5611A?
Q5. Are #25 and #26 of TPA3251 ground pins only for D-channel like #32 and #33 of TAS5611A?
As to PVDD:
Q6. Are #37 and #38 of TPA3251 power pins only for A-channel like #50 and #51 of TAS5611A?
Q7. Is #36 of TPA3251 a power pin only for B-channel like #42 and #43 of TAS5611A?
Q8. Is #31 of TPA3251 a power pin only for C-channel like #38 and #39 of TAS5611A?
Q9. Are #29 and #30 of TPA3251 power pins only for D-channel like #30 and #31 of TAS5611A?
Best regards,
