Hi Keith, Thank you for the timely response. Looking at figure 88, it looks like /RST is tied to DVDD (5 V) through a resistor. What resistance would you recommend if one is needed? Also for a 3 pin configuration I should leave /RVS floating correct? Above figure 56, the datasheet mentions writing to the SDO_CNTL and SDI_CNTL registers to select my SPI protocol. How would I do this in a 3 pin configuration with a grounded SDI pin? Is there some way to configure/calibrate the device with 3 pins, and will the lack of an SDI therefore affect the accuracy of the results? For figure 46, since my CONVST would be tied to my /CS, is the conversion initiated by a falling edge instead? I'm confused about when this quiet period would occur as a result. Thanks a lot for the help, Ian
