TAS5630DKD2EVm and TAS5630PHDEVM Clip Light Continuous on No Audio
I have prepared EVMs boards with the Gerber provided by the TI .
After soldering component One board did started but with strange issue but other two (one with PHD and one with DKD) always show clip light and no audio out . I have used the EVM reference design Inductors from CoilCraft.
The board which did work is showed issue after running for around 1 Hr. Suddenly it started to give some type of cracking noise for example when a loose connection happens in audio source.... It remains even if I remove all external connection. Sometime it goes away for few seconds and again comes back.
I am running with following configuration:
1. 30V /5 Amp Power Supply.
2. 1117-ADj in place of LM317DCY.
3. 12 volt is around 12.1 -12.19 .
I checked all components on all three boards and they seems to be correct and soldered properly.
I don't have clues how to troubleshoot the issues .
The most common problems we see with this device is applying an audio input before the chip is ready, and applying an input signal that is too large for the input of our chip to accept.
I suspect this might be your problem. I also suspect your chips are fried.
