Tool/software:
Hi,
We have received market claims indicating that some units have entered protection mode due to a DC output on one of the speaker channels.
The amplifier in use is the TAS5756.
When measuring each probe at the speaker output and referencing it to the ground chassis, we observed the following waveform:
Similarly, when measuring each probe at the amplifier IC output (before the coil) and referencing it to the ground chassis, we observed the following waveform:
Please note that the I2S waveform is healthy.
Please find the schematic attached below.
Could you please provide any insights into what might be causing this issue?
Thank you.
