General Description
The G1575 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. Each buffer is
capable of driving heavy capacitive loads and offering
large current loading (Vcom: 100mA, Gammas: 30mA).
The G1575 is available in the TQFP7X7-48 and
TQFP7X7-48 (FD) package.
