ISL29012 Data Sheet November 17, 2011 FN6476.2 Light-to-Digital Output Sensor with High SFuenncstitioivnitya,nGdaI2inCSBeulesc™tion, Interrupt The ISL29012 is an integrated light sensor with I2C (SMBus Compatible) interface. It has an internal signed 15-bit integrating type ADC designed based on the charge-balancing A/D conversion technique. This ADC is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The lux range select feature allows the user to program the lux range for optimized counts/lux. In normal operation, power consumption is typically 250µA. Furthermore, a power-down mode can be controlled by software via the I2C interface, reducing power consumption to less than 1µA.
