S9705 Description
Light-to-frequency converter photo IC S9705 series Converts light level to frequency of output pulse The S9705 and S9705-01DT are photo ICs that bine a photodiode and a current-to-frequency converter on a CMOS chip. Output is a square wave (50% duty ratio) with frequency directly proportional to light level incident on the photodiode. The CMOS level digital output allows direct connection to a microcontroller or...
