413101
Visible Light Detector with Analog
and Digital Outputs
DESCRIPTION
The 413101 is a low cost 4-pin visible
light sensor, with a current output which
is directly proportional to the light level.
It has a built in optical filter to provide a
response which is close to the human
eye, or “photopic”. It also has a digital
output to provide on/off switching, with
hysteresis to prevent flicker.
The output current can be converted
to a voltage by connecting it in series
with a resistor. The dynamic range is
determined by the external resistor and
power supply (e.g. 10K and 5V gives a
range of 0 to over 250 Lux, but can be
up to 1000 lux with a 1K resistor). The
internal dark current cancellation
enables high accuracy over the full
temperature range, even at low light
levels.
FEATURES
• Near human eye photopic response
• High IR rejection – integrated optical filter
• Current output highly linear vs light level
• 1uA per lux current output
• External resistor sets linear lux range
• Temperature stable
• Integrated high gain photo-current amplifier
• Dark-current cancellation
• Digital output for on/off switching
• Hysteresis to prevent flicker close to switching
threshold
APPLICATIONS
• Dawn/dusk sensing
• Security lighting
• Night-lights
• LCD backlight control
