TCS3404CS Datasheet PDF - ETC

[TAOS]

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.
