Which QUAD (Or more) 12bit DAC breakout boards with 5v output are readily available in UK?

Using Arduino Audio
1

Today I received an Adafruit AD5693R Breakout Board, I love it, but it is probably overkill on the output bits, 12-bit should be fine.

A 12-bit DAC will do the job, and I want to know which are readily available which have 4 outputs or more, preferrably 5v out option instead of 4.096.

I am using these VIA Arduino to control CV on an Analog synth, so I would prefer the voltage output to be 5v (or higher), and then I can amplify it (and maybe I wouldn't need to).

Is there such a thing as a 5 x i2c board, that would allow me to connect 5 of these at the one time?

Is this the kind of thing you're looking for?

And if you don't want to go the multiplexer route

Both showing as in stock at DigiKey UK.

Looks good, but the MCP4728 seems to output 4.096V using builtin reference voltage, I would prefer higher. I will probably go with that if I don't find another.

The TCA9548A sounds right, how bothersome is it to Multiplex i2c these days with the likes of that?

Thanks for replying :-).

You can select VDD as the reference by setting the configuration bits. The accuracy is then dependent on the stability of VDD.

Hi There. I have a problem. I am using a MCP428 DAC Converter together with different sensorn on a TCA9548A Multiplexer. But unfortunately I can not set the different DAC output channels on the voltages I declare, instead it will always show me 5v on each Channel. Has it got something to do with the settings of the i2c adress or rather with setting on the multiplexer?
My idea is to set the channel values with the data of my sensors (temperature, humidity and so on)
Any help wuld be great!
