about AD828 Video OPAMP

Assuming you need a closed loop gain of 2 or thereabouts, you could look at the AD8002, AD8008, AD8056, AD8062, EL2260, LT1819, MAX4216 or OPA2658.

ICs do not get discontinued in a First-In-Last-Out way, so you can't be sure that an old device like the AD828 will be discontinued before a nominally more recent part. I would suggest choosing the best part for you application but making sure that you use a popular package and pinout. This means that should a part be discontinued it will be easy to drop in a replacement. The 8 pin SOIC package and AD828 pinout are very common.
