Visible Light Detectors (412101,
412102, 413101)
These devices show excellent uniformity and linearity of
performance with various types of light including ambient,
Tungsten Filament, fluorescent and LED lights.
The internal dark current cancellation enables high
accuracy over the full temperature range, even at low light
levels.
Low cost 412xx range
• Analogue design with Digital outputs
• Free from memory effects (such as blooming in the
CdS cells)
• 2-pin visible light sensors
• Current output which is directly proportional to
the light level
• Built-in optical filter to provide a response which
is close to the human eye

413101
• Analogue design with Digital outputs
• Free from memory effects (such as blooming in the
CdS cells)
• 4-pin version
• Digital output to provide on/off switching
• Built in hysteresis to prevent flicker
Application notes:
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. 5V across a 10K resistor gives a range of 0 to 250
Lux but can be raised 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.
The devices can be supplied in probed wafer form, probed
sawn wafer form, or packaged in LED-style or surface mount
packages.
