ISL29003 Light-to-Digital Output Sensor with High Sensitivity, Gain Selection, Interrupt Function and I2C Interface The ISL29003 is an integrated light sensors with a 16-bit integrating type ADC, I2C user programmable Lux range select for optimized counts/Lux, and I2C multi-function control and monitoring capabilities. The internal ADC provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by artificial light sources. In normal operation, power consumption is less than 300µA. Furthermore, an available software power-down mode controlled via the I2C interface reduces power consumption to less than 1µA. The ISL29003 supports a hardware interrupt that remains asserted low until the host clears it through I2C interface. Designed to operate on supplies from 2.5V to 3.3V, the ISL29003 is specified for operation over the -40°C to +85°C ambient temperature range. Block Diagram Features • Range select via I2C - Range 1 = 0Lux to 1000Lux - Range 2 = 0Lux to 4000Lux - Range 3 = 0Lux to 16,000Lux - Range 4 = 0Lux to 64,000Lux • Human eye response (540nm peak sensitivity) • Temperature compensated • 16-bit resolution • Adjustable resolution: up to 65 counts per Lux • User-programmable upper and lower threshold interrupt • Simple output code, directly proportional to Lux • IR + UV rejection • 50Hz/60Hz rejection • 2.5V to 3.3V supply • 6 Ld ODFN (2.1mm x 2mm) • Pb-free available (RoHS compliant) Applications • Ambient light sensing • Backlight control • Temperature control systems • Contrast control • Camera light meters • Lighting controls Pinout ISL29003 (6 LD ODFN) TOP VIEW Ordering Information PART NUMBER TAPE & REEL PACKAGE PKG.
