General Description

The  G1614  consists  of  12+1+1  channel  buffers  target  toward  the  needs  of  thin  film  transistor  liquid  crystal  display  (TFT  LCD).  This  device  incorporates  12  gam-ma buffers, one Vcom buffer and one repair op which can  be  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 (Vcom: 100mA, Gammas: 25mA).

The G1614 is available in the QFN4X4-24 package.
