Low-Power Digital Ambient Light Sensor

with Enhanced Sensitivity

General Description

The MAX44007 ambient light sensor features an I2C

digital output that is ideal for a number of portable appli-

cations such as smartphones, notebooks, and industrial

sensors. At less than 1µA operating current, it is the

lowest power ambient light sensor in the industry and

features an ultra-wide 22-bit dynamic range from 0.025

lux to 104,448 lux.

Low-light operation allows easy operation in dark glass

applications.

The on-chip photodiode’s spectral response is optimized

to mimic the human eye’s perception of ambient light

and incorporates IR and UV blocking capability. The

adaptive gain block automatically selects the correct lux

range to optimize the counts/lux.

The IC includes two I2C slave address options: 1011

010x and 1011 011x.

The IC is designed to operate from a 1.7V to 3.6V sup-

ply voltage range and consumes only 0.65µA in full

operation. It is available in a small, 2mm x 2mm x 0.6mm

UTDFN-Opto package.
