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 âphotopicâ. 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

⢠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
