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 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.
