DESCRIPTION
AA8630
VIDEO AMPLIFIER
AA8630 is a video driver with 6db gain, 75 output buffer and SAG correction ant it
supports 3V and 5V operation voltage. 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 for 6-pin SOT26L.
■
