Hello Javier,
thanks a lot for the answer. For further tests we only used one single primary conductor and with the original DRV421EVM Board, without any changes. We got some good results with the ratio, but only in one single current direction, the results…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 Hi everyone,
we have ordered some evaluation boards from TI and would like to test out this chip DRV421. But we have problem to find proper manufactory for this special core. As it is discribed…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 Hi Team,
Our customer would like to know the sensitivity of this sensor.
And in addition, the customer would also like to understand the point why the coil wires are connected to the PCB board…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 , DRV425 I'm working with the DRV421 evaluation module, attempting to measure a relatively low current of ~50 mA. I'm able to read the signal, but there is also significant noise in the…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 , DRV425 Hello,
I'm trying to test the idea of measuring a very small current signal through a toroid of some sort. I do not want to use a shunt. The current would be on the order of 5 to…
Part Number: DRV421EVM We purchase about ten of DRV421EVM and are examining a current sensor.
From the business and technical aspects,
I would like to discuss directly with the person in charge. I would like to talk directly about the content beyond this…

We have LMG3411EVM-18 daughter boards and we want to use them in closed current loop mode. We found 2 EVMs…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 Hi,
Am developing a residual current sensor 1-20mA AC/DC and having issues with magnetic shielding as well as the minimum sensitivity of the sensor.
1. The Earth's magnetic field causes the…
Hello Christoph,
There is currently not a core off the self with a slot that fits the DRV421 Evaluation Module. I can help you with the design of the magnetic core and go over your design considerations to meet you needs.
