4+1-CHANNEL BUFFER
FEATURES
4+1-Channel: Channels with Output Current
30mA (MAX); Vcom with Output
GENERAL DESCRIPTION
AAT7203 4+1-channel buffer designed thin film transistor liquid crystal display (TFT LCD). This device consists Vcom buffer circuit, rail-to-rail buffer amplifier circuits, buffer amplifier circuits. Each buffer capable driving heavy capacitive loads providing fast load current Vcom 100mA, others: 30mA). AAT7203 comes compact TSSOP14 package, which makes ideal component space-sensitive designs monitors TVs.
Current 100mA (MAX) Unity Gain Buffer Capable Driving Large Capacitive Loads Input Range Matched Reference Requirements
