Are you providing all the supplies to the board - AVDD, DVDD, and IOVDDD?
View ArticleForum Post: RE: ADS8556 channel selection
Hi Arun,Once you pulse CONVST, the BUSY signal should go high indicating that a conversion is underway. Once BUSY returns low, you just strobe the RD input 6 times - basically as shown in Figure 3 on...
