AAT7201
10+1-Channel Buffer for TFT LCD
Features
General Description
z 10 Channels with Output Current: +30mA
(MAX)
z 1 Vcom with Output Current: +100mA
(MAX)
z Unity Gain Buffer Capable of Driving
Large Capacitive Loads

z TQFP48 Package
The AAT7201 is a 10+1-channel buffer
designed to increase the driving capability for
thin film transistor liquid crystal display (TFT
LCD). This device includes a Vcom buffer
circuit, four rail-to-rail buffer amplifier circuits
and six buffer amplifier circuits. Each buffer is
capable of driving heavy capacitive loads and
offering fast current loading ( Vcom : 100mA,
the others: 30mA).
Pin Configuration
AAT7201 comes in a space-saving TQFP48
www.DataSheet4U.com
package, which makes it an ideal component in
LCD TV and monitors.
