„ FEATURE
1. Operating voltage 2.8V~5.5V
2. Composite video driver with 6dB gain
3. SAG correction function
4. Low power consumption, 45mw typical
5. Internal voltage clamp circuit
„ DESCRIPTION
AA8500AP is a video driver with 6dB gain, 75Ω output buffer and SAG
correction. The SAG could reduce the output coupling capacitor. It supports 3V
and 5V operating voltage, and is ideal for video output device, ranging from
portable digital still camera and stationary equipment such as DVD player. The
IC is available in 8-pin TSSOP.
