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.
