IWR1443 : I want a 2-wire current loop level transmitter(4~20mA) reference schematic designed with IWR1642 or IWR1443.

Hi Song,

For Level Sensing the IWR1443 is the recommended part as a low-power solution.

For an IWR1443 2-wire solution we have created the TIDEP-0091 which is optimized for power.

Let me know if you have more questions!

thank you, dear akash!!

I still don't understand.
I can't find any document for the LOOP POWER.

Could you elaborate for 2 wire current loop form 4-20mA loop powered transmitter.
I have two questions.
Is the first TIDEP-0091 working by only 2 wire loop power without any external power source.
Second, I wonder if you support HART protocol.

Thank you for your interest.

Hi Song yong Jun,

Have you seen the power measurements in the Design Guide? We have measured <20 mJ which can also be improved upon.

What specific power requirements do you have?


Cheers,
Akash
