FEATURE

APPLICATION

1. Y/C mix circuit

VCR

2. Output and Chrominance muting function

3. Output protection function

4. SAG correction function

Video Camera

Video Player

5. A load sufficient for driving two circuits

6. Low power consumption, 60mw typical

7. Internal voltage clamp circuit

DESCRIPTION

AA8600AP is a Y/C mix with 6db gain, 75Ω output buffer and SAG correction.

The 75Ω buffer is capable of driving two circuits. The SAG could reduce the

capacitance of output coupling capacitor. The Y signal is clamped input, while the

C signal is biased input. The power saving circuit provides the output and

chrominance muting function. The IC is available in 8-pin TSSOP.

NOTE : Stress above those listed under “Absolute Maximum Rating” may cause

permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those indicated

in the operational section of this specification is not implied. Exposure to

absolute maximum rating conditions for the extended periods of time may

affect device reliability.
