Hi all,

Is there an IC that keeps the polarity the same, no matter how you connect them??

Attached is a diagram to better understand when I mean.

Thanks in advance.

In its simplest form that will be a bridge rectifier. The drawback is that the diodes will produce about 1.2 in voltage drop. For instrumentation purposes you have the "precision rectifier" circuit in many variants. It would help if you told us more about your setting here

 

Thanks for your fast reply. Do you have a diagram of how a bridge rectifier can be used for this application please?

No, i am not going to use this for any project. I was just wondering if there is some sort of IC that can do this.

( BTW sorry for my poor English)

 

Just connect the input at the AC input. The output will have the polarity regardless of how you connect the input

A Bridge rectifier as stated previously
