Ultra-Low Lux, Low Power, Integrated Digital Ambient

Light Sensor with Interrupt Function

ISL29033

The ISL29033 is an integrated ambient and infrared light to

digital converter with I

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 I

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

operation over the -40°C to +85°C ambient temperature

range.
