ISO124: Single Supply Application

Art Mecina

Part Number: ISO124
Other Parts Discussed in Thread: ISO224

Hello Guys,

Good day.

Is it possible to power this device input section with +24V rather than bipolar -12V and +12V? Does Figure 10 of the datasheet can be used for such application?

Thanks in advance!

Hi Art,

No, the ISO124 needs bipolar supplies on both sides. Figure 21 is closer to what you would need to do to run with a single supply.

Thanks for the clarification Tom!

Is there any alternative part you can suggest for the requirements?

Regards,

Hi Art,

Look at the ISO224, single supplies on both sides of the iso barrier!
