Application Diagram—Multi-Channel Delta-Sigma A/D Converter
In a typical single-channel delta-sigma ADC, the system clock is located on the isolated side of the system and only four channels of isolation are
required. With multiple ADCs configured in a channel-to-channel isolation configuration, however, clock jitter and edge placement accuracy of
the system clock must be matched between ADCs. The best solution is to use a single clock on the system side and distribute the clock to each
ADC. The five-channel IL261 is ideal, with the fifth channel used to distribute a single, isolated clock to multiple ADCs as shown below:
