TSL260R, TSL261R,
TSL262R
Infrared Light-to-Voltage Optical
Sensors
General Description
The TSL260R, TSL261R, and TSL262R are infrared
light-to-voltage optical sensors, each combining a photodiode
and a transimpedance amplifier (feedback resistor = 16 MΩ,
8 MΩ, and 2.8 MΩ 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 plastic sidelooker package with an
integral visible light cutoff filter and lens. When supplied in the
lead (Pb) free package, the device is RoHS compliant.
