I am using AD828 Video OPAMP.
AD828 can use Bidirectional Transmission,pls refer to Fig6 of datasheet.
AD828 is excellent amp ,however it's old product.
Do you have other new OPAMPs as same as AD828?.
It would be greatly appreciated if advice could be gotten.
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.
