Luminosity Adjustment for TV Screens, CRT Monitors and Liquid-crystal Display Monitors

Notebook PCs and Portable Information Devices

Cellular and PHS Phones

Other Equipment Requiring Luminosity 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

: ICC = 1 µA (max) @VCC = 5.5 V

● Excellent illumination output linearity

● Luminous efficiency correction filter mounted on detector: λp = 560 mm (typ.)

● Open-emitter output

● Side-view package

● Environmentally friendly silicon used as chip material instead of CdS

Suitable as a substitute for CdS-based products
