The AVDD analog supply for the ADS8688 is generated by converting an unregulated 5-V supply from the
Simple Capture card or by converting an external 5-V supply to a regulated 5-V supply by using the
REG71055 charge pump and the TPS7A4901 linear regulator. The DVDD digital supply for the ADC is
derived from a 3.3-V supply from the Simple Capture card.
