Description
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 × 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 V OR , V OG , and V OB 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 μ m × 378 μ m. 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.
