Hi Kanchan, You will have to program DEVICE_ID_REG register(bits [19-16]) with a unique identification number associated to a device that is used in the daisy-chain configuration, please follow the daisy-chain mode timing in Figure 73 of datasheet, these three configuration data should not be same because different device ID. For normal conversion after configure these two ADC devices properly, three same configuration data(32-bit) can be used to read the conversion data from ADCs, for example, NOP command with all zero data to ADC. Please let me know if you have done this, thanks. Regards Dale
