Function
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
0.3ВµA when powered down. Features 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. Program interrupt feature 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 -40В°C to +85В°C ambient temperature
range. 75ОјA maximum operating current
-0.3ОјA maximum shutdown current Ambient light sensing Simple output code directly proportional to lux Variable conversion resolution up to 16 bits Adjustable sensitivity up to 520 counts per lux Measurement range: 0.0019 to 8,000lux with four
selectable ranges Light sensor close to human eye response
