The part is designed for high resolution TFT LCD panels, and is built on an advanced, high voltage, CBCMOS process. The buffers have high slew rate, 10 mA continuous output current, and high capacitive load drive capability. The VCOM buffer has increased drive of 35 mA and can drive large capacitive loads. The ADD8701 offers wide supply range and offset voltages below 15 mV. The ADD8701 is specified over the –40ºC to +85ºC tempera- ture range and is available in a 32-lead lead frame chip scale package (LFCSP). All inputs and outputs incorporate internal ESD protection circuits. |
