Advanced Analog Technology, Inc. AAT7204 Details are subject to change without notice 6+1-CHANNEL BUFFER FOR TFT LCD FEATURES z GENERAL DESCRIPTION 6+1 Channel: 6 Channels with an Output Current of ± 30mA (MAX); 1 Vcom with an Output Current of ± 100mA (MAX) 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 TSSOP Power PAD-20 & SOP20 Package Available The AAT7204 consists of 6+1 channel buffers target toward the needs of thin film transistor liquid crystal display (TFT LCD). This device consists of a Vcom buffer circuits, two rail-to-rail buffer amplifier circuits and 4 buffer amplifier circuits. Each buffer is capable of driving heavy capacitive loads and offering fast current loading ( Vcom : 100mA, the others: 30mA). The AAT7204 comes in alternative TSSOP Power PAD-20 or SOP20 package. Diversity makes this device an ideal part for LCD monitors and LCD TVs.
