The ISL29033 is an integrated ambient and infrared light-to-digital converter with I2C (SMBus Compatible) interface. Its advanced, self-calibrated photodiode array emulates human eye response with excellent IR rejection. The on-chip 16-bit ADC is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The lux range select feature allows users to program the lux range for optimized counts/lux. Power consumption can be reduced to less than 0. 3μA when powered down. The ISL29033 supports a software and hardware interrupt that remains asserted until the host clears it through the I2C interface. The function of ADC conversion continues without stopping after interrupt is asserted. Designed to operate on supplies from 2. 25V to 3. 63V with an I2C supply from 1. 7V to 3. 63V, the ISL29033 is specified for operation across the -40°C to +85°C ambient temperature range.
