Hello Saeideh,
The TIPD205 does come with a bus bar and with everything pictured here. https://www.ti.com/tool/DRV425-BUSBAR-EVM . This document (users guide) explains the output. https://www.ti.com/lit/ug/tiduaz4a/tiduaz4a.pdf
There is a calculator link…
Other Parts Discussed in Thread: DRV425 Hi E2E,
Here's a quick image with the essential get-it-up-and-running-in-under-5-minutes information for the DRV425 EVM including the pinout and a quick reference to the user guide.

Hello Annie,
The accuracy of these devices can meet the accuracy be the challenge is in the magnetic design. This is where we can limited guidance but the biggest error will come from the magnetic design. The DRV401 is more likely to function better because…
Joachim,
Our DRV425 expert Javier is out on holiday today and tomorrow, as TI observes New Years as a holiday. I have made him aware of your questions, and we will get you some answers Monday when we return to the office.
In the meantime, there is some…
Hello Divyanshu,
The only design guide that uses the DRV425 is http://www.ti.com/tool/TIDA-01467 . This is because all the other use a magnetic core and a magnetic feedback in order to measure the current. They do not use the electrical connection as they…
Hello John,
There will be some minor changes from them depending on there proximity but not much. I would say in lower than there offset of µT. I think other component on the board may impact the more if they are magnetic material as they are normally…
Part Number: DRV425 Hi. We've placed these items in a temperature- and magnetic-controlled chamber for 2 weeks, cycling 5C to 38C:
1) 2 each EVM modules from TI
2) Custom boards with DRV425's (not Q1) using non-magnetic materials and conforming to…
zehua,
The DRV425 is a fluxgate device, which is similar to hall but typically more sensitive. As such, we have found a great way to measure large DC currents with the DRV425 by using two of them inserted into a copper (or other conductive metal) bus…
Jason,
That amount of current is going to be challenging, even implementing on the low side. The issue here is most of our devices are non-isolated solutions.
You could look at something like AMC1300. The measurement inputs top out at 250mV, which means…
Mahfound,
Are the references for both the ADC and the DRV425 driven by the same voltage? Could they be different?
This certainly does look like a thermal settling issue. Looking into what has not settled between the ADC and the DRV425. With such low fields…
