NOA1302
Ambient Light Sensor with
I
Description
sensor (ALS) with a 16−bit ADC and a 2−wire I
The NOA1302 ambient light sensor provides a linear response over
the range of close to 0 lux to well over 100,000 lux with programmable
integration times to optimize noise performance. The sensor employs
proprietary CMOS image sensing technology from ON Semiconductor
which provides low noise and high dynamic range output signals and
light response similar to the response of the human eye.
commands to set options in the device and read out the ambient light
intensity count.

... The major components of this sensor are as shown in Figure 2. The photons which are to be detected pass through an ON Semiconductor proprietary color filter limiting extraneous photons and thus performing as a band pass filter on the incident wave front. The filter only transmits photons in the visible spectrum which are primarily detected by the human eye ...
