GENERAL DESCRIPTION
The ADD8710 is a low cost, 10-channel gamma buffer with a
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
wide supply range and offset voltages below 12 mV.
The ADD8710 is specified over the −40°C to +85°C
temperature range and is available in a Pb-free 28-lead
TSSOP package.
