Description

The TCS3404 and TCS3414 digital color light sensors are designed to accurately derive the color chromaticity

and illuminance (intensity) of ambient light and provide a digital output with 16-bits of resolution. The devices

include an 8

× 2 array of filtered photodiodes, analog-to-digital converters, and control functions on a single

monolithic CMOS integrated circuit. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue

filters, and 4 have no filter (clear). With the advanced patent pending in-package trim capability,

device-to-device and system-to-system tolerance can be minimized allowing very precise repeatability to be

attained.
