High Voltage Interface 

The SIB416 employs the interface circuit shown below between the high voltage input connector, J3, and the anodes of 
the individual SiPMs on the S11064 devices. The monitor output (HVMON) allows the high voltage anode bias to the 
MPPCs to be indirectly monitored at a reduced voltage level. Voltage readings at the monitor point should be scaled by a 
factor of 100. Calibration of the scale factor may be required for very accurate measurements. 

Warning: The high voltage section of the SIB416 contains signals at voltage levels 
that can exceed negative 100 volts. Never touch a component or signal in this area.
