® ISL29004 Data Sheet December 21, 2006 FN6221.0 Light-to-Digital Output Sensor with Address Selection, High Sensitivity, Gain Selection, Interrupt Function and I2C Interface The ISL29004 is an integrated light sensor 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 typically 300µA. Futhermore, an available software power-down mode controlled via the I2C interface reduces power consumption to less than 1µA. The device also support a hardware interrupt that remains asserted low until the host clears it through I2C interface. The ISL29004 is in an 8 Ld ODFN package and has two I2C address pins for multiple devices on the same bus. The ISL29003 is a similar light sensor with a hardwired I2C address that is available in ODFN6 package. Designed to operate on supplies from 2.5V to 3.3V, the ISL29004 are specified for operation over the -40°C to +85°C ambient temperature range. Features • Range select via I2C - Range1 = 1000Lux - Range2 = 4000Lux - Range3 = 16,000Lux - Range4 = 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 • 50Hz/60Hz rejection • 2.5V to 3.3V supply • 8 Ld ODFN (3mmx3mm) • I2C address selection Applications • Ambient light sensing • Backlight control • Temperature control systems Ordering Information PART NUMBER (Note) ISL29004IROZ ISL29004IROZ-T7 TAPE & REEL 7” PACKAGE (Pb-Free) 8 Ld ODFN PKG.
