Re: Digital to Analog Converters

Thanks everyone.

I really don't have the time to develop much hardware(soldering up a whole string of registers). I want to use this system this year, and the deadline is approaching fast...

I do have access to PICs with SPI or I2C interface, in fact, that is what I intend to use. I would like to have a 4 channel output to be able to take advantage of one full port(able to send 4 bytes at a time)

I am looking at D/A converters because I need the full range. Its going to be used for data communications(analog port is the only legal way to get to the RC from the OI). Some one on one of the other threads said that digital pots have a +/- 30% resistance variability so...

I was looking at some Maxim DACs, and they seem like they would get the job done. Any specific suggestions on what types or features I should be looking for? I just need something that I can get going with fast!

Thanks
