4 Channels with an Output Current of
mA30± (MAX); 1 comV with an Output Current of mA100± (MAX) z Unity Gain Buffer Capable of Driving Large Capacitive Loads z Input Range Matched to LCD Reference Requirements z DDV Specified for 6.5V to 16V z TSSOP14 Package 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 comV 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 ( comV : 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. PIN CONFIGURATION TOP VIEW TSSOP14
