Hello Everyone,
I am working on AD7730 interface with msp432p401r controller. I give AVDD=+5V,AGND=DGND=ground,DVDD=+3.3V because controller required 3.3V so no external voltage convertor circuit required.But, when i give DVDD 3.3V the voltage suddenly goes increase upto 4.5V means at DVDD pin it shows 4.5 V. why?? if supply given to DVDD is 5 v then ic work properly.plz help??
