The output of each channel is a voltage that is linearly proportional to light intensity (irradiance) on the corresponding photodiode element.
Gain is switchable via a digital input pin from 1× to 4× on the TCS3104, and from 2× to 4× on the TCS3103 (as compared to 1× of TCS3104).
Each channel on the device consists of a photodiode with a red, green, or blue optical filter, a current-to-voltage converter, and gain control elements.
The voltage from each of the red, green, and blue channels is output on the VOR, VOG, and VOB pins, respectively.
The single MFP pin controls the gain for all three channels.
Each of the three photodiode channels is split into three elements, which are dispersed in a 3 × 3 array.
This makes the device less sensitive to non-uniform illumination across the sensing area.
The overall photodiode active area is 378 μm × 378 μm.
Each channel is factory-trimmed for low dark offset voltage and uniform sensitivity from device-to-device.
The TCS3103 and TCS3104 are intended for use in a variety of applications including color-point feedback control in solid-state illumination and backlight systems, color adjustment in printers, process controls, diagnostic systems, paper and product handling, toys, and games.
