Optical FusionRGB-IR-Ambient and
Temperature Sensing
MAX44006
*
/MAX44008
*
The MAX44006/MAX44008 integrate ve optical sen sors in each of two products:
red, green, blue (RGB) sensors; an ambient light (clear) sensor; and an ambient
infrared sensor with an I
2
C interface. These sensors include ve parallel ADCs to
provide faster and noise-immune measurements. These highly integrated optical
sensors also include a temperature sensor to improve reliability and performance.
Benefits
• Optical-thermal fusion provides
multiband performance in a small
footprint
◦ 6 sensors (5 optical + 1 thermal) in
parallel
◦ 1.5ms to 100ms ADC integration
time offers speed vs. resolution
flexibility
◦ Tiny 2mm x 2mm x 0.6mm package
• Reliable measurements over a wide
range of environmental conditions
◦ 50/60Hz immunity for robust
readings
◦ IR rejection for RGB sensors provides
high-performance RGB reading
◦ Front-end temperature
compensation for reliable
measurements
• High-level integration reduces time to
market
◦ Integrated interrupt and persist
features off-load work from
microcontroller
◦ I
2
C digital communication provides
noise-immunity at the interface
◦ 1.8V to 5.5V wide supply voltage
range is easy to interface wide range
