The part is designed for high resolution TFT LCD panels and is built on an NC NC advanced, high voltage CBCMOS process. 1 OUT1 IN1 The gamma buffers have a high slew rate, minimum 10 mA output current, and a high capacitive load drive capability. The 2 IN2 OUT2 VCOM buffer is capable of delivering 250 mA of peak current and can also drive large capacitive loads. The ADD8710 offers a 3 IN3 OUT3 wide supply range and offset voltages below 12 mV. The ADD8710 is specified over the 40C to +85C tempera- 4 OUT4 IN4 ture range and is available in a Pb-free, 28-lead TSSOP package. 5 OUT5 IN5 6 IN6 OUT6 7 OUT7 IN7 8 OUT8 IN8 9 OUT9 IN9 10 OUT10 IN10 OUTCOM V INCOM COM GND GND Figure 2.
