The CXLC8980 consists of 14+1 channel buffers target toward the needs of thin film transistor liquid crystal display (TFT LCD). This device incorporates one Vcom buffer and 14 gamma buffers, and are programmed through I2 C interface. It contains two register banks which can store two different sets of gamma reference values. Each buffer is capable of driving heavy capacitive loads and offering large current loading (Vcom: 100mA, Gammas: 25mA). The CXLC8980 is available in the TQFN5X5-32 package.
