Overview

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 combine 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 other logic circuitry.
The S9705 series has wide dynamic range and light level can be easily measured when used with a digital counter.
Features Converts light level to frequency Wide dynamic range: 5 orders of magnitude Excellent linearity Output timing reset function Digital output for direct interface to microcontroller 4-pin plastic package Applications Liquid crystal monitor backlight dimmer for mobile devices Brightness adjustment for large-screen liquid crystal TV Lighting dimmer Replacement for CdS photoconductive cells Absolute maximum ratings Parameter Symbo...
