Description :

Advanced Analog Technology, Inc. AAT7200/A Details are subject to change without notice 14+1-Channel Buffer for TFT LCD Features z z z z z z 14-Channels with Output Current: +30mA (MAX) One channel Vcom with Output Current: +100mA (MAX) Unity Gain Buffer Capable of Driving Large Capacitive Loads Input Range Adjusted to Match TFT LCD Requirements General Description 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). .
