Other Parts Discussed in Thread: TAS6422E-Q1
Hi, TI support team
The customer used the TAS6422-Q1 to create a circuit diagram with PBTL.
Since there is no PBTL application SCH on the DATASHEET of the TAS6422-Q1, the circuit diagram was created by referring to the circuit diagram of the TAS6422E-Q1.
Please review the circuit for the PVDD power supply side and the Audio output (Filter circuit) side.
[customer's SCH - TAS6422-Q1 PBTL]
[TAS6422E-Q1 PBTL Application SCH]
[TAS6422-Q1 BTL Application SCH]
Q. In the PBTL circuit of the TAS6422E-Q1, pins 55 and 56 are NC, but should they be treated as NC when used as PBTL in the TAS6422-Q1?
Q. Is there a possibility that a defect will occur if it is not treated with NC?
Q. Please tell us about the power sequence of TAS6422-Q1 (timing information).
Thanks.
Regards,
MJ
