Mobile Phones, PHS, Pagers Notebook PCs, PDAs Video Cameras, Digital Still Cameras Other Equipment Requiring Luminosity Adjustment
The TPS850 is a linear-output photo-IC which incorporates a photodiode and a current amp circuit in a single chip. This photo-IC is current output type, so can set up output voltage freely by arbitrary load resistance. · · · · · · High sensitivity: IL = 230 µA @EV = 100 lx (typ.) Using the fluorescent light Little fluctuation in light current : Width range = x1 to x1.6 (typ. ±25%) Output linearity of illuminance is excellent Open-emitter output Compact and light surface-mount package Pb-free TOSHIBA Weight: 0.017 g (typ.)
