General Description

The G1632 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 I2C 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 G1632 is available in the QFN5X5-32 package.
