MAX44007
Low-Power Digital Ambient Light Sensor
with Enhanced Sensitivity
General Description
The MAX44007 ambient light sensor features an I 2 C
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.
Features
S Wide 0.025 Lux to 104,448 Lux Range
S Small, 2mm x 2mm x 0.6mm UTDFN-Opto
S V CC = 1.7V to 3.6V
S I CC = 0.65μA Operating Current
S -40 N C to +85 N C Temperature Range
S Improved Sensitivity Behind Dark Glass
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.

PIN-PACKAGE TEMP RANGE
6 UTDFN-Opto-EP* -40 N C to +85 N C
The IC includes two I 2 C 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.
Applications
Tablet PCs/Notebook Computers
+ Denotes a lead(Pb)-free/RoHS-compliant package.
* EP = Exposed pad.
