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. FUNCTIONAL BLOCK DIAGRAM VS ADD8710 VS NC NC OUT1 1 IN1 OUT2 ...
