412101
Visible Light Detector
DESCRIPTION
The 412101 is a low cost 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”.
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 (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
• Temperature stable
• Integrated high gain photo-current amplifier
• Dark-current cancellation
APPLICATIONS
• Dawn/dusk sensing
• Security lighting
• Display backlighting in laptops, mobile phones,
LCD TVs
• Night-lights
