ISL29002
Data Sheet December 1, 2006 FN7465.2
Light-to-Digital I2C Sensor
The ISL29002 is an integrated light sensor with a built-in integrating type ADC and a standard I2C interface. The device transforms illuminance, ambient light level in lux, into a digital output signal accessible through I2C. The sensor precisely converts illuminance from 1lux to 100,000lux. The ADC features up to 15-bit effective resolution. The sensor includes another photodiode covered with metal to reduce the effects of dark output reading that may be significant in low lux levels. The ISL29002 can control display panel backlighting depending on ambient light conditions, adding artificial intelligence by approximating the response of a human eye.
