Color/proximity sensor
P12347-01CT
Color sensor, proximity sensor, and 3-color LED
incorporated into a single package
This is a multifunctional sensor that incorporates a color sensor, proximity sensor, and 3-color LED in a small package (5.5 ×
1.7 × 1.0 mm). It can be used to adjust the display image quality, perform touchscreen on/off control, indicate incoming calls,
and so forth on smartphones and the like. The color sensor not only detects the RGB ratios of ambient light but also functions
as an illuminance sensor. This feature enables image quality to be adjusted in fine detail. In smartphone applications, the
proximity sensor detects when a face draws near and turns off the touchscreen function and the LCD backlight. We provide an
evaluation kit for this product as well as an evaluation board. Contact us for detailed information.

*1: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
*2: When driven externally
*3: Duty ratio ≤ 10%, pulse width ≤ 0.1 ms
*4: Moisture absorption and reflow conditions: JEDEC J-STD-020D LEVEL3
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
