GND V_DD OUT
The TSL253R is a light-to-voltage optical sensor combining a photodiode and a transimpedance amplifier
(feedback resistor = 16 MΩ) on a single monolithic IC. Output voltage is directly proportional to the light intensity
(irradiance) on the photodiode. The device has improved amplifier offset-voltage stability and low power
consumption and is 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.
