what are those signals going to be used for?
anyways, if you want a -/+ 5V or -/+ 10V signal, i assume you have some bipolar power supply? well, probably you don't, if you were using that phidgetAnalog thing. (amazing, it costs 90$ and the page doesn't seem to say which DAC is being used?)
at any rate, a bipolar supply (+/- 12v, +/- 15v) would make things easier. so let's assume you have one, you can then simply use basic op amp circuits to scale your signal. DAC datasheets usually have bipolar output examples, though details might somewhat depend on what it is that you want to do (eg. is DC accuracy important, or not so much).
then there's various options re: choice of DAC. if you want/need high(ish) sample rates, you're probably looking at SPI not i2c. MCP4822 must be the most popular one; these are dual so you'd need three (CLK, MOSI, 3 x CS). if you're comfortable with SMD, there's way more choice, including quad and octal DACs, even bipolar DACs (AD5721R, for instance, though that's just single channel, so not very suitable).
