Would You Be Interested in RoadTesting an Analog Output Module with Adaptive Power Management (Reference Design)?

This quad-channel, analog output module delivers voltage and current outputs using the highly integrated DAC8775 digital-to-analog converter (DAC). Integrated adaptive power management, along with the LM5166 buck converter, reduces the total power dissipation of the reference design to less than 1 W, even when driving all four channels at 20 mA simultaneously.

Features

<1-W of Total Power Dissipation driving all four-channels at 20-mA
<0.1 %FSR of Total Unadjusted Error in either Voltage or Current mode
8-µA of Peak-to-Peak Current Output Ripple
200-µV of Peak-to-Peak Voltage Output Ripple
Adaptive Power Management for Current Outputs

Nahh, details, details
It does raise an important point though that I have mentioned on various discussions in the past, before anyone applies to a road test for items like this (Any product really). Ensure you have the abilities to actually test it, this includes required equipment, suitable microcontroller, Multimeter, Oscilloscope in some cases etc. and also personal skills, it is not enough to just perform an unboxing and recite the user guide. We dont need a road test for that.

Yes, its something top play with it. It another thing to make _use_ of it and integrate it into a real project. A four-channel-DAC with 4-20mA current output is something you don't need that often. Oh, and you need to program that by yourself with a MCU.

Difference in backgrounds of the members will play a key role.

As a maker/hobbyist, it sounds like chinese to me, so I'm not interested. An actual engineer like you will think the complete opposite

WOW, i'm surprised not more folks are interested in this item, it looks like a fun part to play with and to integrate into some IOT based project...

I guess it can be made more compact to fit the factor forms of industrial D/A modules. It would be interesting to control it from a Raspberry Pi acting as a PLC.

Pretty nice industrial 4-20 mA (or+- 10V) quad analog output card for factory automation. Here is the datasheet .
