Advanced Analog Technology, Inc. AAT7203 Details are subject to change without notice 4+1-CHANNEL BUFFER FOR TFT LCD FEATURES 4+1-Channel: 4 Channels with an Output Current of ± 30mA (MAX); 1 Vcom with an Output GENERAL DESCRIPTION The AAT7203 is a 4+1-channel buffer designed for thin film transistor liquid crystal display (TFT LCD). This device consists of a Vcom buffer circuit, two rail-to-rail buffer amplifier circuits, and 2 buffer amplifier circuits. Each buffer is capable of driving heavy capacitive loads and providing fast load current ( Vcom : 100mA, and the others: 30mA). AAT7203 comes in a compact TSSOP14 package, which makes it an ideal component for space-sensitive designs of LCD monitors and LCD TVs. Current of ± 100mA (MAX) Unity Gain Buffer Capable of Driving Large Capacitive Loads Input Range Matched to LCD Reference Requirements VDD Specified for 6.5V to 16V TSSOP14 Package PIN CONFIGURATION TOP VIEW TSSOP14 – 台灣類比科技股份有限公司 – – Advanced Analog Technology, Inc. – Page 1 of 9 V 0.1 Advanced Analog Technology, Inc.
