Hi Eren,
Welcome to the E2E forum! It does appear that the ADS122C04 is recognizing the addressing but not the command. A couple of things to check and make sure that the AVDD and DVDD supply are both at nominal operating voltage, and that the RESET pin is set high and not floating.
What value of pullup resistor are using on the I2C lines? What are your power supplies for AVDD and DVDD? Have you tried slowing the communication by using a slower SCL speed?
Best regards,
Bob B
Hi Bob,
The problem is about AVDD supply. After figure it out the problem is solved. Thanks for your response.
