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?

  • Could you use a normal buck/boost... whatever and make the output voltage a bit higher...

    Then use a LDO after, followed by a large polymer low ESR capacitor.

    Most noise is due to bad PCB layout not the converter itself.

    You need split ground planes and never mix signal return with power ground
