DESCRIPTION
AA8622AP
Dual Video Amplifier
AA8622AP is a dual video amplifier with 6db gain, 75Ω output buffer and SAG
correction. The 75Ω 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
Composite video driver with 6dB gain
Dual channels video amplifier
Output short circuit protection function
SAG correction function
A load sufficient for driving two circuits
Low operating current, 25mA typical
Internal voltage clamp circuit
8-pin TSSOP package
