AAT7200/A

14+1-Channel Buffer for TFT LCD

Features

General Description

z 14-Channels with Output Current: +30mA

(MAX)

z One channel Vcom with Output Current:

+100mA (MAX)

z Unity Gain Buffer Capable of Driving

Large Capacitive Loads

z Input Range Adjusted to Match TFT LCD

Requirements

z VDD Specified for 6.5V to 16V

z TQFP-48 Package

Consisted of 14+1-channel buffers, the

AAT7200 is designed to increase the driving

capability for the needs of the thin film

transistor liquid crystal display (TFT LCD).

This device includes a Vcom buffer circuits,

four rail to rail buffer amplifiers circuits, and

10 buffer amplifiers circuits. Each buffer is

capable of driving heavy load and offering fast

current loading ( Vcom : 100mA, the others:

30mA).
