AMS302

Light Sensor (AMS1, 3) Cadmium-free sensor with spectral response The Through-hole Type for easy implementation as a CdS cell replacement SMD type LIGHT SENSOR TYPICAL APPLICATIONS 1. Brightness detection for LCD backlight control for LCD devices (mobile phones, LCD TVs, car navigation systems, mobile PCs, and PDAs). 2. Brightness detection for controlling the keypad backlight in mobile phones. 3. Brightness detection for circuits in household lighting, crime prevention lighting, and automatic lighting for bicycle. 4. Brightness detection for wall clocks (radio clocks). FEATURES 1. Built-in optical filter for spectral response similar to that of the human eye. Peak sensitivity wavelength is 580 nm 1.0 NaPiCa spectral Human spectral Relative sensitivity L 2.0mm .079inch W 3.2mm .126inch H 1.0mm .039inch 1 Amplifier 4 0.8 2 3 0.6 12 Anode 34 Cathode 0.4 www.DataSheet4U.com Through-hole type 0.2 0 300 400 500 600 700 800 900 1000 1100 Wavelength, nm 5.0 mm dia. .197 inch dia.
