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.
