PCM1861: differential input - missing n or p channel doesn't make a difference

PCM1861: differential input - missing n or p channel doesn't make a difference

Part Number: PCM1861

Hello,

A friend suggested using the single ended measurement option of PCM1861 along with differential mode.

So first measure p and n channels seperately in single ended mode

then measure it in differential mode.

if all 3 measurements are okey then we conclude the signal is fine

what do you think?

    Hi, Rifo,

    This approach might be used, as this analysis will dictate if all the connections to the differential input are fine. It will be a matter of selecting the device inputs used for each test by updating MD2, MD5 and MD6 configuration pins.
