Output voltage is directly proportional to IR light intensity (irradiance) on the photodiode. The TSL267 has a transimpedance gain of 320 MΩ. The device has improved offset voltage stability and low power consumption and is supplied in a 3-lead visible-light-blocking plastic sidelooker package with an integral lens.

Measured with RL = 10 kΩ between output and ground. Optical measurements are made using small-angle incident radiation from a light-emitting diode (LED) optical source. The input irradiance is supplied by a GaAs light-emitting diode with the following characteristics: peak wavelength λp = 940 nm. Irradiance responsivity is characterized over the range VO = 0.1 V to 4.5 V. The best-fit straight line of Output Voltage VO versus Irradiance Ee over this range will typically have a positive extrapolated VO value for Ee = 0. 6. Power supply rejection ratio PSRR is defined as 20 log (ΔVDD(f)/ΔVO(f)) with VDD(f = 0) = 5 V and VO(f = 0) = 2 V.
