Hi,
In our product, the TAS5825M receives I2S signal from a wireless audio module, the sample rate of the input I2S is 46.87KHz.
When the audio source stops play, the I2S carries a low noise, the level is approximately -90dBFS.
But in this situation, the TAS5825M output has an obvious noise that can be heard from 1 meter away.
The power supply level of the TAS5825M is 20V, max output power is 30W@4Ohm, the noise RMS level is 1.2mV
Could you please give some advice on how we should check the problem?
Thanks!
