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. Features ● Programmable Interrupt Function with User-Defined Upper and Lower Threshold Settings ● Internal Filter Eliminates Signal Fluctuation Due to AC Lighting Flicker — No External Capacitor Required ● In-Package Trim Provides an Easy and Accurate Means to Achieve System-to-System Repeatability ● 16-Bit Digital Output with I2C at 400 kHz ● Programmable Analog Gain and Integration Time Supporting 1,000,000-to-1 Dynamic Range ● SYNC Input Synchronizes Integration Cycle to Modulated Light Sources (e.g. PWM) ● Operating Temperature Range −40C to 85C (CS Package) −30C to 70C (FN Package) ● Operating voltage of 2.7 V to 3.6 V ● Available in Both an FN and a CS Package. The CS Package is the Industry’s Smallest Digital RGB Color Sensor Applications ● Provides Method to Derive Chromaticity Coordinates to Manage Display Backlighting (i.e. RGB LED, CCFL, etc.) ● Provides Means to Derive Color Temperature to White-Color Balance Displays Under Various Lighting Conditions End Products and Market Segments ● HDTVs ● Tablets, Laptops, Monitors ● Medical Instrumentation ● Consumer Toys ● Industrial/Commercial Lighting ● Industrial Process Control
