MAX44005
RGB Color, Temperature,
and Infrared Proximity Sensor
General Description
The MAX44005 integrates 7 sensors in one product: red,
green, blue (RGB) sensors; an ambient light (clear) sen-
sor; a temperature sensor; an ambient infrared sensor,
and an infrared proximity sensor with an I²C interface.
This highly integrated optical sensor includes a tempera-
ture sensor to improve reliability and performance.
The IC computes all the light information with parallel
data converters to make simultaneous light measurement
in a very short time. The chip consumes only 15FA in
RGBC + IR mode and operates at 1.8V supply voltage.
The IC’s RGB sensing capability improves the perfor-
mance of end products by providing robust and precise
information for ambient color sensing and color tempera-
ture measurement.
The integrated proximity sensor uses a single-pulse LED
scheme to achieve very low power consumption. This
method also improves sunlight rejection and 50Hz/60Hz
noise to deliver reliable proximity measurements. With this
technology, the IC is a perfect solution for touch-screen
portable devices and presence detection applications.
The on-chip ambient sensor has the ability to make wide
dynamic range 0.002~8388.61FW/cm² measurements.
The IC’s digital computation power provides program-
mability and flexibility for end-product design. A pro-
grammable interrupt pin minimizes the need to poll the
device for data, freeing up microcontroller resources,
and reducing system software overhead, and ultimately,
power consumption. All these features are included in a
tiny, 2mm x 2mm x 0.6mm optical package.
