GENERAL DESCRIPTION FUNCTIONAL BLOCK DIAGRAM
The ADD8710 is a low cost, 10-channel gamma buffer with a
VS ADD8710 VS
VCOM driver that operates from a single supply. The part is designed for high resolution TFT LCD panels and is built on an
NC NC
advanced, high voltage CBCMOS process. The gamma buffers have a high slew rate, minimum 10 mA
1 OUT1 IN1
output current, and a high capacitive load drive capability. The
2
V
OUT2 IN2
COM buffer is capable of delivering 250 mA of peak current and can also drive large capacitive loads. The ADD8710 offers a
OUT3 3 IN3
wide supply range and offset voltages below 12 mV. The ADD8710 is specified over the −40°C to +85°C tempera-
OUT4 4 IN4
ture range and is available in a Pb-free, 28-lead TSSOP package.
