Loop Powered Isolator

HARANATH VASAM1

Other Parts Discussed in Thread: ISO1212, ISO1211

I am looking for loop power isolator for 4 to 20mA current measurement. Isolation Required: 2KV.

Please suggest suitable part. Suggested part need not be pin to pin compatible as we are designing new board. We need functionally equivalent part.

Currently we are using LP420(data sheet attached).

Haranath,

We do not have something that is functionally equivalent. The closest thing we have to this is the ISO1212 or ISO1211. These are loop powered but are used for digital input/output.

Respectfully,

Lucas Schulte
