The TSL261R-LF is an infrared light-to-voltage Optical Sensor combining a photodiode and a trans-impedance amplifier (feedback resistor=8MR) on a single monolithic IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. This device has improved amplifier offset-voltage stability and low power consumption and are supplied in a 3-lead plastic side-looker package with an integral visible light cut-off filter and lens.
