TSL250R, TSL251R,
TSL252R
Light-to-Voltage Optical Sensors
The TSL250R, TSL251R, and TSL252R are light-to-voltage optical
sensors, each combining a photodiode and a transimpedance
amplifier (feedback resistor = 16M, 8M, and 2.8M
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.
Ordering Information and Content Guide appear at end of
datasheet.
