Hello Holger,
The decision for no EVM I cannot comment on. I would suggest the customer build their own PCB like the DRV421 but keep in mind that the package is different. DRV401 is 5mm x 5mm and the DRV421 is 4mm x 4mm. I would look at the DRV421EVM…

My customer is looking for the current sense amplifier which can measure up to 250A.
I read the E2E link below ;

Hi Brice,
In a 75kW system at 600V, the maximum current you should see will be 125A, so a ~1.5mΩ resistor should be sufficient to measure the current. This would be less than 0.2V of drop across the resistor or 25W. This is the maximum value, I expect…
Hello A_M,
See my replies below.
Akio Murita said: Q1: why the table and the figure show different voltage? which one do I need to refer to?
The figure is a typical device tested over temperature. This will not show the distribution. The 250mA in…
Part Number: DRV411 Other Parts Discussed in Thread: DRV425 , DRV401 , DRV421 , DRV5013 , DRV5055-Q1 Hello,
I need a solution to measure a static magnetic field up to 15mT. The challenge is to find a solution with a very low drift on the gain sensitivity…
Part Number: DRV401 Hello!
i have a question, if the DRV401 is in normal operation,and the measured current is 250A, now, i set the Demag pin to high at least 25.6 μs to start a Demag cicle. in this situation， the probe circuit will still work normally…
