FAQ. How to ensure synchronization of conversion between multiple AD7124-4/AD7124-8 devices?

Answer: To ensure synchronization between multiple AD7124-4/AD7124-8 devices, the same master clock must be used for all devices. If the AD7124 internal clock has been used, then one ADC serves as the master and uses its own internal clock and this clock is made available on the device CLK pin. This clock is used as the external clock source for other ADCs. To synchronize the sampling instant /SYNC pin can be used to control the start of conversion alternatively a common command such as enabling continuous conversion will reset the conversion process at all parts. It will only have the 1MCLK uncertainty between conversions of different devices.
