MAX44004

Digital Ambient Light Sensor

General Description

Benefits and Features

The MAX44004 is a wide dynamic range, low-

power ambient light sensor (ALS) ideal for many light

sensing applications: tablets, displays, accessories,

medical devices, and light management systems.

S Consumes Low Power

ꢀ5µA Supply Current

ꢀInterrupt Pin Delivers Efficient Communication

S High Sensitivity

The on-chip ambient sensor has the power to measure

the exact visible light from 0.03 lux to 65,000 lux and com-

municate through an I²C digital communication bus. The

IC has patented sensors, filters, and circuitry to mimic the

human eye response. With on-chip calibration registers,

it performs the same in different light conditions (i.e., fluo-

rescent, incandescent). The interrupt pin minimizes the

need of constant polling of the device, freeing up micro-

controller resources for efficient communication and thus

reducing overall power consumption. The part-to-part

matching is optimized by proprietary Maxim process to

speed up end-product development time.

ꢀ0.03 Lux Sensitivity

S Easy to Design

ꢀ1.7V to 3.6V Supply Voltage

ꢀTight Part-to-Part Variation

S Reliable Light Sensing

ꢀPerfect Rejection of 50Hz/60Hz Noise

ꢀAdjustable Visible and Infrared Sensor Gain

S Tiny, 2mm x 2mm x 0.6mm OTDFN Package

S -40°C to +105°C Temperature Range

Ordering Information appears at end of data sheet.

The IC can operate from a V

of 1.7V to 3.6V, including

both supply and I²C times. It consumes just 5µA operat-

ing current.
