    Considering...

    1) Use an isolated driver such as the ADM2486 with an isolated 100mW 5V-5V
    DC-DC converter.

    2) Use my standard 485 driver (LT1785) and power it with an isolated 100mw
    5V-5V DC-DC converter and use 3 opto-couplers for the data and enable lines.

    Are there advantages to one approach or the other?
    Which opto-couple should I use for #2?

    thx
