Light and Proximity Sensors
Part Description Features Benefits
Ambient Light Sensors
MAX44009 Ambient light sensor with
industry’s lowest power
< 1µA operating current. 1.7V to
3.6V supply, 0.045 lux to 188,000
lux range, rejects IR and UV, 22-bit
dynamic range
Provides optimal visual display
brightness.
Proximity Sensors
MAX44000 Proximity and ambient light sensor Integrated IR LED driver and
receiver
IR LED pulsing avoids proximity
errors from extraneous IR sources.
RGB Sensors
MAX44006*, MAX44008* RGB color sensor, IR sensor,
temperature sensor
Six sensors in one package provide
reliable true-color digitization
Ease design of color temperature
measurement systems.
Sensor Signal Amplifiers
Part Description Features Benefits

industrial applications
4.5V to 36V operation, 125µV V
OS
,
0.94nV/√Hz input voltage noise,
55MHz BW, shutdown mode
Provides ultra-low noise
amplification to ease detection of
very small sensor signals.
MAX44251 Dual op amp with auto zero
for ultra-high DC precision in
industrial applications
2.7V to 20V operation, 6µV V
OS
,
5.9nV/√Hz input voltage noise,
5MHz BW

amplification to maintain system
accuracy.
MAX9636/7/8 Op amp with low input bias
current
0.8pA input bias current, low 36µA
supply current
Ultra-low input bias current keeps
low signal levels valid in smoke
detectors and other wireless
sensors.
