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.
Other Parts Discussed in Thread: DRV421EVM , DRV421 Hi,
I observed two problems during testing of DRV421EVM.
1) As shown in below figure if I connect let say S2 (in kit) to CL2 (compensation coil over core) and S1 to CL1, board takes 10mA while on interchanging…
Hello Mohamed,
All we have is the DRV421EVM that you can order. This does not include the compensation coil but it does have a Shunt resistor that may need to be adjusted for you current levels.
