As seen in the SiPM digital control board netlist, the ICs on the control board have many different power requirements. This page suggests some compatible voltage supplies that will be necessary on the board. To reduce the number of backplane connections and the number of external supplies needed, some of these supplies might be created using voltage dividers on the control board.

+210V supply

Use for:

  • AD5535 DAC
    • VPP high voltage supply (for SiPM bias voltages)

+5V supply

Use for:

  • AD5535 DAC
    • V+ amplifier supply pins
    • AVCC analog supply pins
    • DVCC digital supply pins
  • AD7314 temperature sensor
    • VDD supply
      • indicates ±1°C accuracy
  • AD7928 ADC
    • AVDD pins
      • indicates measuring range of 0 to 2xREF_IN voltage

-5V supply

Use for:

  • AD5535 DAC
    • V- amplifier supply pins

+3.3V supply

+2.5V supply
