General Description

The  G1620  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  pro-grammed 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 load-ing (Vcom: 100mA, Gammas: 25mA).

The G1620 is available in the TQFN5X5-32 package
