ISL29033

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.
