Light-to-frequency converter photo IC
The S9705-01DT is a photo IC that combines 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 intensity incident on the photodiode. The CMOS level digital output allows direct connection to a microcontroller or other logic circuitry. The S9705-01DT has wide dynamic range and light intensity can be easily measured when used with a digital counter.
-Converts light intensity to frequency
-Wide dynamic range: 5 orders of magnitude
-Output timing reset function
-Digital output for direct interface to microcontroller
