4 Power Supplies

The ADS8568EVM has four power supplies: AVDD (5 V), DVDD (3.3 V), HVDD (15 V), and HVSS (-15 V). The two high voltage power supplies require an external ±15 V supply and are connected on a screw terminal strip (J9). The lower voltage supplies (AVDD and DVDD), are generated with the USB power and low dropout regulators (LDO).
