Variable gain and stable detection even at high gains
Along with an APD, current-to-voltage conversion circuit, and high-voltage power supply circuit, the C10508 contains a microcontroller to perform
temperature compensation based on information from the internal thermosensor. Because temperature coefficients that match the APD temperature
characteristics are written in the microprocessor chip, the APD can be operated with a highly stable gain over a wide temperature range even at high
gain levels. The gain can be changed by the switch on the board or a command from a PC.
