SiPM digital control board power supplies (view source)
Revision as of 19:33, 25 June 2008
, 19:33, 25 June 2008→+3.3V supply: added AD5535 ANODE connection
Use for:
Use for:
*AD5535 DAC
*AD5535 DAC
**ANODE
***Used for temperature monitoring. Voltage drop across a temperature sensitive diode allows AD7928 to measure internal temperature of AD5535. External resistor on AD5535 CATHODE will help to limit current draw.
**REF_IN supply
**REF_IN supply
***Using +3.3V for REF_IN limits the SiPM amplifier bias voltages to a maximum of 165V. If greater variability is needed (up to +200V max), a separate +4V supply can be used for REF_IN, perhaps taken from the +5V rail via a voltage divider.
