The CXLC8979 consists of 12+1+1 channel buffers target toward the needs of thin film transistor liquid crystal display (TFT LCD). This device incorporates 12 gamma buffers, one Vcom buffer and one repair op which can be programmed through I2 C interface. It contains two register banks which can store two different sets of gamma and VCOM values. Each buffer is capable of driving heavy capacitive loads and offering large current loading (Vcom: 100mA, Gammas: 25mA).?
