Color Light-to-Frequency Converter
The TCS3200 / TCS3210 color light-to-frequency converters interface directly with a microcontroller or DSP and are available in an 8-pin SoIC package. The output is a square wave and frequency directly proportional to light intensity. The full-scale output frequency can be scaled by one of three pre-set values via two control input pins.
* Communicates directly with a microcontroller
* Pin-selectable colour
* Pin-selectable output scaling
* Power down
* Stable temperature coefficient of 200 ppm/ºC
