I've just got back to thinking how to drive piezo sounder, and was
wondering if something like the Natsemi LM4908 headphone amp working
in bridge mode would be ok.
The piezo has a 18nF capacitance
The lm4908 seems a lot easier and smaller than brewing my own

Any potential gotcha's?

Can you pass on the spec *** for your piezo buzzer?? Many of these have
on-board stuff that works just fine with a TTL signal.
