Light Sensor Ic/ambient Light Sensor Ic/visible Light Sensor

详情

Light to Voltage Sensors
        A range of low cost visible light sensor ASICs with a current output which is directly proportional to the light level. 
        They show excellent uniformity and linearity of performance with various types of light including ambient, tungsten filament,fluorescent and LED lights.
        The devices are supplied in *-pin packaged LED style or SMD, especially designed to replace CdS cell as a result of the RoHS initiative.

 Features:

Analogue design with Digital outputs. 
Free from memory effects(such as blooming in the CdS cell).
Near human eye photo pic response.
High IR rejection.
Temperature stable.
Integrated high gain photo-current amplifier.
Dark-current cancellation.

Applications:

Dawn/dusk sensing
Security lighting ( surveillance camera)
Display back-lighting in laptops, mobile phones, LCD TVs
Night-lights/ Solar-lawn lamps
