Part Number: DAC8771EVM I'm sorry it's a rudimentary question.
I want to check just basic DAC work through the DAC8771EVM and DAC8771EVM Software.
Using the SM-USB-DIG as the DVDD supply.
Connecting a a12V power supply to PVDD/AVDD.
And I applied…
Joost,
The DAC8742HEVM wasn't designed specifically to be placed inside a 4-20mA loop. I would note that the device operates on a 6V maximum supply, so if it is in a loop, the power supply should probably be independent. In the loop, the DAC8742H can…
Maynard,
It shouldn't be a problem for the device to run off of the loop power. In that case, you would use some LDO to drive VPOS_IN, AVDD, and PVDD from the same voltage. It's important that all of them are tied together to the same point. It would…
Hi Paul-san,
On the current output line, DAC8771EVM has 15 ohm resister while our board has 60 ohm. Does this difference cause the rise of VPOS_IN and AVDD current consumption?
I also tried Auto Learn Mode. Test load is 750 ohm, 21mA output. When I set…
Part Number: DAC8775 Other Parts Discussed in Thread: DAC8771EVM , Hi Team,
I have designed my own application board using DAC8775. Configuration and voltage levels look ok, but I am not able to read status register and see outputs on the terminals.
I…
Part Number: DAC8771 Other Parts Discussed in Thread: , DAC8760 Team,
My customer has a question on 12-36 for PVDD/AVDD to GND for the DAC8771:
I was hoping to use an unregulated supply coming from a transformer which should deliver 13-16 VDC during normal…
