The TCS3103 and TCS3104 RGB Light-to-Voltage Converters combine three photodiodes with optical filters,
amplifiers, and gain-switching circuitry on a single chip. 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
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 V
the three photodiode channels is split into three elements, which are dispersed in a 3
device less sensitive to non-uniform illumination across the sensing area. The overall photodiode active area
is 378 μm
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.

TAOS108B − JULY 2010 Detailed Description The TCS3103 and TCS3104 devices output a voltage that is linearly proportional to light intensity in the spectral range of interest on each of the three sensor channels. Figure 2 shows how each sensor responds to light of various wavelengths. The peak response of each of the three channels roughly corresponds to blue, green, and red portions of the visible light spectrum ...
