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).
