1. DESCRIPTION

The ADA4417-3ARMZ-R7 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 ADA4417-3ARMZ-R7 can handle the most demanding HD video applications. The ADA4417-3ARMZ-R7 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 Ω terminated loads, either dc- or ac-coupled. The ADA4417-3ARMZ-R7 also has an output dc offset function that can operate in two states. When the DCO pin is tied to VCC, the video signal at the output is offset by 200 mV. When the DCO pin is tied to ground, the output dc level follows the input level. The ADA4417-3ARMZ-R7 is available in a 10-lead MSOP package and is rated for operation over the extended industrial temperature range of −40°C to +85°C.
