I'm considering using one of the Linear Technology push-pull driver chips, e.g. LT1533, LT1683 or LT3439. At over $4 they are pretty pricey, so I'm looking for alternatives. Do ADI have anything equivalent?

Oliver,
for low noise you may want to consider a resonant topology rather than a forced push pull. Unfortunately we do not have any product in this power class for you.
If you are still interested in a forced push pull then you can reduce noise by using the ADuM3070 as a gate driver and adding external HV FET. You would control the switch speed (and noise) with gate drive impedance (a resistor) in series with the FET gate.
Best of luck,
LucaV
