New Hamamatsu 12-bit Digital Colour Sensor Photo IC

Hamamatsu Photonics introduce a new digital RGB colour sensor Photo IC, the S11012-01CR. This new device features a monolithic CMOS IC with three 12-bit digital registers, allowing simultaneous measurement of RGB values at 615nm, 540nm and 465nm. The new IC is supplied in a compact and high reliability chip-on-board (COB) package.

The photodiode consists of 9 x 9 elements arrayed in a mosaic pattern. Each element has an on-chip filter that is sensitive to one colour of light and light detected by the photodiodes is amplified and converted into 12-bit digital signals. The amplifiers are formed for each of the RGB photodiode elements, allowing simultaneous accurate measurement of the RGB components of the incident light.

To enable measurement over a wide range of illuminance, the photodiode sensitivity can be selected from two setting modes; high sensitivity mode and low sensitivity mode. Depending on the mode chosen, either 9 x 9 elements or the central 3 x 3 elements will be active. This gives the S11012-01CR a very useful wide dynamic range.

The new devices compact size (3.43 x 3.8 x 1.6 mm) and simplicity of integration makes it ideal for LCD backlight and RGB-LED brightness adjustment in flat panel televisions and mobile phones.
