Advanced Analog Technology, Inc. AAT7201 Details are subject to change without notice 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) 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 z Unity Gain Buffer Capable of Driving Large Capacitive Loads z Input Range Matched to LCD Reference Requirements z VDD Specified for 6.5V to 16.0V z TQFP48 Package Pin Configuration 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). AAT7201 comes in a space-saving TQFP48 package, which makes it an ideal component in LCD TV and monitors.
