H-Bridge for continuous(rather than digital) driving?

[Jeff Johnson]

Are H-Bridges always bi-stable or do they generally simply translate the
input voltage into the output voltage? Since they are almost exclusively
used for switching I would imagine they are designed for such. I would like
to use them for level translations in a continuous way if possible(it would
be simpler than rolling my own).

The bridge itself isn't necessarily bistable. That's a feature of the
controller. An H bridge is basically two bridged class AB amplifiers when
driven in their linear region. Dissipation issues will have to be
considered for such operation of course.

Yes, I meant the H-Bridge driver and not the H-Bridge itself.
