TPS850 TOSHIBA Photo IC Silicon Epitaxial Planar TPS850 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 t.
