Hello!
In my device I use example schematics given in TAS5508C datasheet. On XTL_OUT there is a voltage varying from 1.8V down to 1V. On XTL_IN There is voltage from 0 to 200mV, and no resonant frequency present. All 3.3 and 1.8 voltages are present and ok. Current consumption is at ~10...20 mA, periodically increasing to 30mA.
What can be the source of the problem?
