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 2 C (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 I 2 C
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
I 2 C supply from 1.7V to 3.63V, the ISL29033 is specified for
operation over the -40°C to +85°C ambient temperature
range.
