Hi All,
I have looked about but can't find a multi-channel DAC that's compatible with Arduino. I need at least 8 channels and 8-bit is fine as is quite a low sample rate. They are being used to provide CV outputs for a synth.
Does anybody know of anything? 4 channels would be OK as long as I can hook two of them up at the same time. I have found lots of single-channel boards but no joy on the multi-channel.
Thanks in advance
Hello EurekaTech
Take a view here:
Ah thanks, Paulpaulson, I suppose I might have to resort to building it myself but time constraints mean I was looking for a pre-built board and one that would be relatively easy and quick to get going on an Arduino Due.
Nice one though
What is the problem with connecting more than one of them to an Arduino?
You can multiplex just about any type of communication.
Are you familiar with the MCP48XX and MCP49XX series?
Communicates over SPI so pretty fast.
I haven't found any that will allow me to easily connect 8. i.e running out of IC2 channels. Plus I did think about multiplexing but that would make the waveform a bit choppy and as its for music even if it was very high frequency I wanted separate DACs
These look good only up to 2 channel though, looking for 8
But guess it would be easy enough to connect 4 of them, and there is an Arduino Lib, cool. Thanks
Still, if anybody has any of the shel solutions that would also be great.
