The ANX5104 is a low cost visible light sensor, with a current output which is directly proportional to the ambient 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 400 Lux, but can be over 2k Lux with a 1K resistor). The internal dark current cancellation circuit enables a stable accuracy over the full temperature range, even at low light levels.
l High IR Rejection w/ embedded optical filter
l High Current Output Linearity vs Ambient Light Level
l Temperature stable
l Integrated photo-current amplifier
