Do ADI offer a low noise push-pull driver?

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,
