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.

The LUMENOLOGY /C0114 Company www.taosinc.com MANUFACTURING INFORMATION Moisture Sensitivity Optical characteristics of the device can be adversely affected during the soldering process by the release and vaporization of moisture that has been previously absorbed into the package molding compound. To ensure the package molding compound contains the smallest amount of absorbed moisture possible, each device is dry-baked prior to being packed for shipping. Devices are packed in a sealed aluminized envelope with silica gel to protect them from ambient moisture during shipping, handling, and storage before use. The FN package has been assigned a moisture sensitivity level of MSL 3 and the devices should be stored under the following conditions: Temperature Range 5 °C to 50°C Relative Humidity 60% maximum Total Time 6 months from the date code on the aluminized envelope — if unopened Opened Time 168 hours or fewer Rebaking will be required if the devices have been stored unopened for more than 6 months or if the aluminized envelope has been open for more than 168 hours. If rebaking is required, it should be done at 50°C for 12 hours. ams AG Technical content still valid
