General Description
The G1603 consists of 12+1 channel buffers target
toward the needs of thin film transistor liquid crystal
display (TFT LCD). This device incorporates one
Vcom buffer and 12 gamma buffers, and is pro-
grammed 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 load-
ing (Vcom: 100mA, Gammas: 25mA).
The G1603 is available in the QFN4X4-24 package.
