Part Number: TAS5717 Tool/software: Hello：
During the customer's attempt, we have encountered some issues. Please provide some technical guidance. Thank you!
Now it is found that the I2S input has a signal but no output. Which registers need to be…
Part Number: TAS5717 Hi,
I was searching for power on/off sequencing requirements for the TAS5717 amplifier. The Datasheet seems to miss this out completely, but I found this thread which references the TAS5713M Datasheet Figure 69:

Part Number: TAS5717 Hi team,
Customer apply IIS to TAS5717 and found that when no DOUT, there is abnormal output on OUT_A and OUT_B as shown, which cause noise at speaker. I also attached schematics for your reference. Could you pls help to review it…
Thanks Damian for the pointers. We looked at the supplies and apparently, we are observing a dip in the voltage as much as to 2.4V from 3.3V due to load on the rail.
This voltage dip is resulting in Audio PA reset and hence the OSC TRIM register back…
Part Number: TAS5717 Dear Sir
The TI TAS5717PHPR, IC OS-RES and resistance R32 mentioned above, now we have made 13 sets before the batch of 1000 sets, and R32 uses 16K. After our test, 8 pieces of audio were normal, but 5 pieces of audio were interrupted…
Part Number: TAS5717 Hi,
We have used TAS5717 Audio PA for driving two 10W, 8 Ohm speakers in our design. We would like to get the layout reviewed before we release the design for fabrication.
Please find attached the layout file in .brd format for review…

Dear Expert
A batch of 1500 was produced, with a small number of boards, and the audio was intermittent and sometimes silent when the pin16 resistance is 18.2K. Touching this resistor with your hand will produce a reaction, sometimes…

Hi,
We are bringing up speaker out using TAS5717 in our custom board. All the power supplies, I2C and the I2S interfaces are up. But we are unable to see any output on the speaker or any waveform.
The schematics is below:
We also…
