The ROM series from Raytron is an IR optical sensor which receives the wireless signal sent by the infrared(IR) transmitter and converts it to the initial signal waveform using the amplifying-waveform shaping circuit.
This helps the machine operate the way it was intended by a set or device. The product has built-in photodiode and pre-amp IC in a package.
1. Description
The RAL-Series Photo IC, consisting of photodiode and a current amp circuit in a single chip.
This photo IC is a cost effective solution to the power saving of display back lighting of mobile
application such as the mobile phones and PDAs.
The photodiode peaks in human luminosity curve at 600nm.
Hence, it provides an excellent responsivity.
2. Application
- Detection of ambient light to control display back lighting mobile devices-mobile phones PDAs computing devices,TFT LCD TV, plasma TV, video camera, digital still camera
- Automatic residential and commercial lighting management
- Automatic contrast enhancement for electronic signboard
- Ambient light monitoring device for daylight and artificial light
3. Features
