Hi all
I'm involved in the design of some fairly high-end audio equipment for which we need to include a balanced audio line output; I'm looking to use the DRV134, but was hoping someone with more experience than me (i.e. probably most of you!) could give their opinion on the best (in terms of performance rather than cost/efficiency) way of deriving a +/-18V supply from a single 5V rail (the device in question will be USB-powered).
Parts cost is less of an issue than audio performance, but unfortunately my limited background in audio design means I don't know if there's a generally accepted way of doing this well!
Many thanks
Angus
