VCOM driver that operates from a single supply. The part is
designed for high resolution TFT LCD panels and is built on an
advanced, high voltage CBCMOS process.
The gamma buffers have a high slew rate, minimum 10 mA
output current, and a high capacitive load drive capability. The
VCOM buffer is capable of delivering 250 mA of peak current and
can also drive large capacitive loads. The ADD8710 offers a …
