Hi People!

 

 

I'm trying to use AD7710 to acquire temperature value from PTC1000 with a wheatstone bridge. I connected the ADC with this configuration:

My problem is with the crystal (MCLKIN and MCLKOUT). I use a 10MHz crystal and the power supply is 5.05 VDC to AVdd and DVdd (the same source). MCLKOUT send 2.5 VDC to crystal and it not generates any clock signal. Which is the problem? May be I must use two capacitors with the crystal?
Sorry for the text mistakes...
Thanks for all!
