DDC232: Use of DDC232 with SiPM (avalanche photodiode)

Hello Mike,

I wanted to let you know that our expert on this device is out of the office for Christmas and New Year holidays, he will be back in the office on 1/3/22.

Thank you for your patience.

Hi Mike,

Thanks for the patience.

With my limited knowledge on the SiPM sensor, I do not see why not. However, can you please help to describe what kind of signal you expect from the SiPM avalanche photodiode connected to the DDC23?. Your attached diagram shows it will be a current pulse that needs to be converted to a voltage pulse with the ADC.

The DDC232 operates based on integrating the input current for a specific amount of time and convert the charge collected to digital output with the ADC. Please refer to the DDC232 datasheet for the device's basic operation and see if it is suitable for your application.

Thanks

Hi TC,

Please see the SiPM operation at the following link:

What is an SiPM and how does it work? | Hamamatsu Photonics

Also, what is the maximum current that we can have at the analog input of DDC232?

Regards,

Mike
