Part Number: ISO1228 Other Parts Discussed in Thread: ISO7741 , ISOM8710 , ISO1212 , , ISO7740 , ISO7741EVM Tool/software:
I am using three AC/DC programmable power supplies (HDS3000-12) in parallel for my application. Each…
Hi Gabriel,
Thanks for your patience while I was out of office for the US holidays.
Manny is correct - I did conduct this experiment on ISO7741EVM but it would work for any ISO77xxEVM. The power supplies used do not have to be isolated. I also tried…
Hi Bobby,
The input termination resistor is not necessary. On our newer EVMs (ISO7741EVM and ISO7842EVM) we have not included it. For most applications it is fine to just connect the digital isolator channels to the microcontroller directly. I'm sorry…
Hey Mark,
The maximum working isolation voltage for the ISO772x in the D package is 637VDC. This can be found in Section 6.6 Insulation Specifications in the ISO7721 datasheet
I quickly recreated the setup you described in the labs here in Dallas…
Hi Jim,
I hope you have found a solution that meets your requirement. If you are still looking for an EVM that supports multi-channel isolation of digital CMOS signals then you look at using an EVM from ISO77xx family of devices, the ISO7741EVM. This…
