I am attempting to use the AD7606. I have configured the board for serial output.

The test results show that the EOC(End of Conversion) is HIGH for 600us after inputting the CONVST signal.

 Initial conditions are as follows:  

 

Avcc                5.01
Vdrive                3.30
OS[2:0]            High
\PAR/SER/BYTE SEL   High
\STBY            High
RANGE            Low    for using +/-5V
CONVST            High
RESET            Low
SCLK                Low
\CS                Low
FRSTDATA            Low
DB[13:9] & DB[6:0]        tied to Analog ground

DB[15:14] & DB[6:0]        tied to ground

 

 

Add the configured circuit.
