The ISL29002 is an integrated light sensor with a built-inintegraTIng type ADC and a standard I2C interface. Thedevice transforms illuminance, ambient light level in lux, intoa digital output signal accessible through I2C. The sensorprecisely converts illuminance from 1lux to 100,000lux. TheADC features up to 15-bit effecTIve resoluTIon. The sensorincludes another photodiode covered with metal to reducethe effects of dark output reading that may be significant inlow lux levels.The ISL29002 can control display panel backlighTIng dependingon ambient light conditions, adding artificial intelligence byapproximating the response of a human eye. The ISL29002can also manage portable peripheral illumination based uponlighting conditions extending battery life.In normal operation, the ISL29002 consumes less than 300μAof supply current. A software power down mode is controlledvia the I2C interface and disables all but the I2C interface. Thesupply current is then reduced to less than 88μA.Designed to operate on supplies from 2.5V to 3.3V, theISL29002 is specified for operation over the -40°C to +85°Cambient temperature range. It is packaged in a clear, Pb-free8 Ld ODFN package.
