MODULE Color sensor module C9303-04 RGB-LED backlight monitor for TFT-LCD (Liquid Crystal Display) Recently, RGB-LEDs have been in the focus of attention as the backlight for TFT-LCD (liquid crystal display) since LEDs are mercury-free unlike conventional cold cathode fluorescent lamps. Hamamatsu C9303-04 color sensor module has been specifically developed for the power monitor of RGB-LEDs. We welcome requests for custom shapes and RGB gain. Feel free to contact our sales office. Features Applications l Built-in RGB color sensor Sensitivity matches wavelengths of RGB-LED backlight for TFT-LCD. l 3 ch current-to-voltage amplifiers Simultaneous output of 3 ch RGB photocurrent l Configuration and size suitable for side mounting to TFT-LCD l Suitable for lead-free solder l Pin compatible with previous device l Low current consumption l RGB-LED backlight monitor for TFT-LCD ■ Absolute maximum ratings (Ta=25 °C) Parameter Supply voltage Reference voltage Operating temperature *1 Storage temperature *1 *1: No condensation Symbol Vcc VREF Topr Tstg Value +5.5 Vcc - 0.4 -20 to +85 -20 to +85 Unit V V °C °C ■ Electrical and optical characteristics (Ta=25 °C, Vcc=5.0 V, VREF=3.000 V, unless otherwise noted: 1 ch) Parameter Symbol Spectral response range λ Peak sensitivity wavelength λp Photo sensitivity Trans-impedance Output offset voltage Output voltage range Output signal polarity *2 Output noise voltage swing SR SG SB ZtR ZtG ZtB Vos Vout Vout Vn Condition Red Green Blue Red Green Blue λp=620 nm λp=540 nm λp=460 nm Red Green Blue Dark state Dark state, within frequency bandwidth 10 to 90 % -3 dB Dark state Rise time tr Cut-off frequency fc Current consumption Icc Operating supply voltage range Vcc *2: See next page graph (■ Output voltage vs. input light).
