AK4113 input question

To connect coax RCA to the board, is the square top IN1 via GND or positive?

Thanks very much and Happy New Year!

Are asking if the square pad is GND?

If so, it is and it can be determined by the thermal reliefs i.e. the crosses that connects the pad to the ground plane. Its there to be able to solder the pad as if there where no "cross", one would her a very hard time heating the pad as the ground plane would be one large heat sink.

But you write "is the square top IN1 via GND or positive?" which is a really strange sentence so I'm not surer about my answer...
  • is IN1 a square top - this is what you might be saying...
  • do one reach IN1 (whatever that would be...) via GND or positive (pad?)
  • is the IN1 via, a GND or a positive... could be another interpretation....
