has anyone used the AD5624R DAC?
« on: June 04, 2024, 02:43:02 am »
I want a 16 bit DAC on a JLC populated PCB and most of the usual suspects seem to be out of stock or ridiculously expensive (DAC1220 DAC8562, both which I wrote drivers for).
As this one seems pretty cheap and easy to get I am wondering what's wrong with it for a slow DC output?

I was planning on using the chinky GP8211S,  (which I also just write an esp-idf driver for https://github.com/mianos/GP8XXX/blob/main/main/gp8.h)
But I can't even see a supplier for that one, aside from the DFRobot board that I already got (that's flawed in that it oscillates on the 5V range without a lot of extra output capacitance).

Or maybe just tell me "use the Ti parts and stop messing about dumbass".

Nothing wrong with it. It's a good DAC from Analog Devices, with specs similar to the DAC85xx series from TI.

I use DACs from that series pretty often and they are just fine. However, the AD5624R is 12-bit, not 16 as you said you need!

Yes, the AD5664R is the 16-bit one.

But since the OP compared it with the DAC8562, which IIRC is 2-channel DAC (and the DAC8564 the 4-channel version?), maybe they have the numbers confused, and meant to pick a 2-channel, 16-bit DAC in this AD56 series? In this case, the 2-channel, 16-bit one would be the AD5689R, for instance.

Yes sorry, looking at the common data sheet that has all 3, the AD5664R: 16 bit

I just want a single channel, 16 bit that is easily available for stuffing by JLPCB.
The DAC1220 is 20 bit and my favourite.

Thanks all. I was mainly asking as there does not seem to be as much support on github for the AD56 series and they seem really good.
I'd write my own driver, github just a measure of popularity outside hard core in house use.
I only need 1 channel but the 4 channel one seems much more available.
