Dual Video Amplifier
DESCRIPTION
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 .
