[PD] Using custom analog devices with PD

[PSPunch]

Hi all,


I know many of you integrate analog circuitry and custom
made gadgets with the PD domain, perhaps heat or pressure
sensors.

I was wondering if there was an orthodox method of hooking these
up to a system running PD.
Is there such a thing as a 1-chip "voltage to RS-232C converter"
or anything of a similar kind ?
