Interfacing microcontroller with +/- 10V?

[Texton]

Hi guys.

I have to design a interfaceboard for my microcontroller (PSoC5 - 3.3V). The interface board should have +/- 10V in/out and a minimum bandwidth at 48kHz.

My plan for the output right now is to control mosfets with the microcontroller which opens and closes for the 10V.

But before I begin to build and test anything, I wanted to see if you guys had some suggestions/tips on how to interface the microcontroller with other voltagelevels, both in and out?

clamp it up and level shift to something manageable.

With a +/- 10v voltage range you maybe about to use a standard RS-232 transceiver, like the MAXIM series.

An important question would be, what are you driving with the +/- 10v side?
