(MAX)
z 1 Vcom with Output Current:
+100mA(MAX)
z Unity Gain Buffer Capable of Driving
Large Capacitive Loads
z Input range Matched to LCD Reference

General Description
The AAT7200 consists of 12+1 channel
buffers target toward the needs of thin film
transistor liquid crystal display (TFT LCD).
This device consist of a Vcom buffer circuits,
four rail to rail buffer amplifiers circuits and
8 buffer amplifiers circuits. Each buffer is
capable of driving heavy capacitive loads and
offers fast load current (Vcom : 100mA, the
others : 30mA).
