GENERAL DESCRIPTION

The ADD8701 is a low cost, 12-channel buffer amplifier and 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 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.
