The AVDD analog supply for the ADS86xx 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.
