we are using the ADAU1761 with headphone and speaker on outputs.
The speaker is connected via SSM2377 amplifier to the LOUTN/LOUTP pins, which are set as line out.
The headphone is connected as ground-centered to RHP/LHP pins using decopling capacitors.
We have got a problem of pops during AVDD switching on or off.
We have seen, that the outputs of HP and speaker are biased with AVDD/2 after switching on the AVDD power supply.
Is there any possibility to suppress the pops independently of applying the AVDD supply voltage?
Maybe there is a possibility to disable the AVDD/2 bias to analog outputs, or other cirquit popless solutions.
Please, give us some advices.
Thanks very much.
