5 、 Video Filter : ADA4417-3
The ADA4417-3 is a low cost, fully integrated, video reconstruction filter specifically designed for
consumer high definition video. With 1 dB frequency flatness out to 38 MHz, and 44 dB of rejection at
75 MHz, the ADA4417-3 can handle the most demanding HD video applications. The ADA4417-3
operates on a single 3.3 V to 5 V supply. It is well-suited for applications where power consumption is
critical. A disable feature allows for further power conservation by reducing the supply current to 10
µA (typical) when the device is not in use. With rail-to-rail output, it can be efficiently used on a 3.3 V
supply, while providing the user with a 2 V p-p output. The buffers can drive two 75
terminated
loads, either dc- or ac-coupled.
