Adjustment
The TPS818 is a linear-output (current output type)
photo-IC which incorporates a photodiode and a current amp
circuit in a single chip. A luminous efficiency correction filter
mounted on the detector ensures accurate luminosity output
levels. The device’s excellent output linearity enables
automatic adjustment of the luminosity of a TV screen or PC
monitor in accordance with the ambient brightness of the
operating environment.
· High sensitivity
: Light current IL = 240 µA (typ.) @EV = 100 lx
· Little fluctuation in light current
: 1.67 times width (±25° typ.)
· Low current consumption
