TSL250R, TSL251R,
TSL252R
Light-to-Voltage Optical Sensors
General Description
The TSL250R, TSL251R, and TSL252R are light-to-voltage optical
sensors, each combining a photodiode and a transimpedance
amplifier (feedback resistor = 16MΩ, 8MΩ, and 2.8MΩ
respectively) on a single monolithic IC. Output voltage is
directly proportional to the light intensity (irradiance) on the
photodiode. These devices have improved amplifier
offset-voltage stability and low power consumption and are
supplied in a 3-lead clear plastic sidelooker package with an
integral lens. When supplied in the lead (Pb) free package, the
device is RoHS compliant.
