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 , V , and V pins, respectively. The single MFP pin controls the gain for all three channels. Each of

OR OG

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.
