General Description
AA8672 is a video driver which integrates 6dB gain rail to rail output driver, 3rd low pass filter and coaxial communication receiver. The VREF (pin8) can set the threshold voltage of the receiver by external circuit. It supports +2.5V and +5.5V operating voltage, and is ideal for video output device such as surveillance camera. The AA8672 can be DC-coupled or AC-couple with input video signal, such as the output stage of DAC to eliminate out-of-band noise. The output can drive DC-couple or AC-couple signal (150£[) or dual (75£[) loads.
