4 Power Supplies

The PHI provides multiple power-supply options for the EVM, derived from the computer USB supply. The EEPROM on the ADS8900BEVM uses a 3.3-V power supply generated directly by the PHI. The positive and negative supplies are derived from the 5.5-V regulated supply from the PHI (EVM_REG_5V5).
