The ADD8701 is a low cost, 12-channel buffer amplifier and V 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 m A continuous output current, and high capacitive load drive capability. The V buffer has increased drive of 35 m A and can drive large capacitive loads. The ADD8701 offers wide supply range and offset voltages below 15 m V.
The ADD8701 is specified over the
- 40ºC to +85ºC temperature range and is available in a 32-lead lead frame chip scale package (LFCSP). All inputs and outputs incorporate internal ESD protection...
