Single-Channel Isolated Delta-Sigma A/D Converter
This circuit illustrates a typical single-channel delta-sigma ADC. The A/D is located on the bridge with no signal conditioning electronics
between the bridge sensor and the ADC. In this case, the IL717 is the best choice for isolation. It isolates the control bus from the
microcontroller. The system clock is located on the isolated side of the system.
