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).
1 Vcom with +100mA(MAX) Output Current: Unity Gain Buffer Capable of Driving Large Capacitive Loads Input range Matched to LCD Reference Requirements Specified for -20oC to +85 oC…6.5V to 16V TQFP-48 Pins Pin Configuration TOP VIEW – Advanced Analog Technology, Inc.
