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.
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.
