Hi Alexandre, Sorry for the delay in responding. I will also respond to your other post shortly. For this post, I am assuming that you are using the TMDSCNCD28069 (the non-ISO version). This setup is possible. I have some thoughts on it though:
For…
Other Parts Discussed in Thread: ISO7220C , ADS1203 , AMC1200 For example, in ISO7220C,
I can find VDE, CSA, and UL information, and in VDE(IEC 60747-5-2),
Basic Insulation
Maximum Transient Overvoltage, 4000 VPK
Maximum Surge Voltage, 4000…
Brett:
Both sides were tested, and they looked the same, there are no triggering captured by the oscilloscope.
But maybe that doesn't mean the ISO7220c are still good, because there are no variations in the waveforms?
Anyway I dont know how CCS…
Carlos Miguel Espinar said: the problem was in the digital isolator ISO7220AC
Hello Carlos,
My board also uses ISO7220A, and I got this solution from the forum

Problem found and resolved.
In the implementation of the emulator, based on the Experimenter's kit , four optocouplers were added to interface with ControlCARD.
The error was the specification for the optocouplers: ISO7220A (1 Mbps signaling rate…
Brett:
You were riight, it was hardware. We used the wrong version of the ISO7220 chip. We used ISO7220A with a 410ns propogation delay, but TI used the ISO7220C with a 36ns propogation delay. We changed the chips and we were back in the saddle. We…
Part Number: DAC161S997 Other Parts Discussed in Thread: , TPS61045 HI sir
I use the DAC1612997 For 4-20mA output is ok, when power loop is from external power supply
but if i want to use the USB power to supply the 24 v, did you have any suggestion…
Jan, We've used the xds100v2 with isolation on some of our boards, and most notably on the F28M35x controlCARD (whose schematics can be found in controlSUITE). As long as you use iso7220c or -m you should be able to get some speed improvement over the…
Conor,
I will work to get answers on the above, but our systems and product teams are still largely out for the holiday, so it may take some time to run this down.
As far as I am aware. I do not believe we have a published certificate specifically…
