My customer wants to use PCM1774 an they do have some questions, maybe you can help.
They would not use AIN1L and AIN1R.
1: What is the recommendation for this two inputs ?
2: is there a recommendation for Ground connections ?
3: Can we connect Analog ground to Digital ground ?
4: The package PCM1774 has a thermal PAD, is it internally connected to Analog ground or Digital ground ?
5: is there another App note or datasheet for other audio DAC components, that describes layout support?
Thank you kind regards,
