DESCRIPTION
AA8622AP is a dual video amplifier with 6db gain, 75 output buffer and SAG
correction. The 75 buffer is capable of driving two circuits. The SAG could
reduce the output coupling capacitor. The power saving circuit provides the
power saving function. The IC is available in 8-pin TSSOP package .
FEATURES
1. Composite video driver with 6dB gain
2. Dual channels video amplifier
3. Output short circuit protection function
4. SAG correction function
5. A load sufficient for driving two circuits
6. Low operating current, 25mA typical
7. Internal voltage clamp circuit
8. 8-pin TSSOP package
