First you need a Sega Dreamcast Emulator (For original Sonic Adventure) or a Gamecube Emulator (For Sonic Adventure DX, which is an upgrade of the original). After that you need to download the emulator AND the ROM for the game you want to play. Note that the emulators are not Nintendo/Sega approved or licensed.
Sonic Adventure does.
"Sonic Adventure" was originally created for the Dreamcast, and is now available in the PlayStation Network and XBox Live. "Sonic Adventure DX" is an enhanced version of the original game for the Gamecube and Windows.
No, you cannot directly download Sonic Adventure DX for the GameCube, as it is a physical game released on disc. However, if you own the game, you can play it on a GameCube console or use a compatible emulator on a PC, provided you have a legal copy of the game. Additionally, it is available for download on other platforms, such as the Nintendo eShop for Wii or Wii U.
