General Description
The G1606 consists of 16+2 channel buffers target
toward the needs of thin film transistor liquid crystal
display (TFT LCD). This device incorporates 2 Vcom
buffers and 16 gamma buffers, and is programmed
through I2C 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
(Vcoms: 100mA, Gammas: 25mA).
The G1606 is available in the QFN5X5-28 package.
