Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421
Hi Team,
Posting on behalf of our customer.
My question arises from designing the core and introducing an air gap. When adding an air gap the inductance of the secondairy winding drops…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 Tool/software: Hi Team,
My customers would like to evaluate DRV421 and use it to test a current from 0-24mA with resolution of 0.01mA and accuracy below 0.2%. Currently they have applied…
Part Number: DRV421EVM Other Parts Discussed in Thread: DRV421 , Hello everyone,
as I was asking about the suitable core for the DRV421 Evaluation Board, later we found one company who has succesfully produced this core for us. (see below).
The core…
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…
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 system…
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…
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…
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…
