[Applications] Ambient light sensor
Available in a small 2mm x 2mm x 0.6mm UTDFN-Opto package. The MAX44009 ambient light sensor provides I2C digital output and is ideal for portable products such as smartphones, notebooks, and industrial sensors. Operating at less than 1μA, the device is the industry's lowest power ambient light sensor with an ultra-wide dynamic range of 22 bits (0.045 lumens to 188,000 lumens).
Ideal for working in dark glass environments due to the ability to detect extremely faint light.
The spectral response of the on-chip photodiode is optimized for the human eye's response to ambient light, integrating infrared and UV shielding. The adaptive gain circuit automatically selects the correct lumen range optimization test (count value/lumen).
The IC is designed to operate from a 1.7V to 3.6V supply voltage range and consumes only 0.65 μA at full load.
