Part Number: DAC7760 Other Parts Discussed in Thread: DAC8760EVM , TIPD153 Dear Sir,
Can you please explain the following points :-
What is loop compliance Voltage , how to measure the same.
It has been mentioned that "AVSS TIED TO GND". Can you…

Dear Technical Support Team,
I have a question about “DAC8760EMC-EVM”. I have a concern about the noise immunity of DAC8760…
Also, there is a TI design that describes this EVM with a little more detail. You can find the design folder here:

Hello,
Please provide a schematic for your design for me to evaluate.
Otherwise, I suggest you consider referring to our reference design in TIPD153 ( http://www.ti.com/tool/TIPD153 ). Though the document does not publish surge test results it was…
Nakai-san,
I would say my suggestion is that the HART-IN pin is AC coupled to GND as we have demonstrated in the EMC/EMI reinforced reference design ( https://www.ti.com/tool/TIPD153 ), however this is not necessarily required. This is just the optimal…
Hello Kazuya,
The DAC8750 is designed to operate under both IOUT open circuit and short circuit to ground conditions. When IOUT is open circuit, an IOUT fault alarm will be generated to notify the user of the fault. The device does not get damage regardless…
Yulei,
What is the DAC8760 hardware platform that this test is being conducted on? An EVM board? An EMC-EVM board? Custom hardware? If it's custom hardware, can you share the schematic? RF artifacts may not entirely be dependent on devices soldered…
Hi,
The DAC8760EMC-EVM is basically one of the TI designs that we had described here:
https://www.ti.com/tool/TIPD153
Within the folder, you can find the BOM, schematics, and the gerber files.
There is also a guide describing this project…
Hello,
It sounds like you're familiar with at least one of the TI Designs related to the DAC8760 - there are several floating around ti.com from various groups within TI. The TI Design (tidu392.pdf) you mentioned uses one approach to deliver IEC61000…
Hi John,
Is it safe to assume this is the same IEC61000-4 ESD test setup? Is there a specific configuration which is leading to the failure (i.e. air vs contact). What voltage level are you applying to the design? I am just trying to assess how 1:1…
