Hello Varatharaj,
The bandwidth of one of our hall sensors DRV5053 is 20kHz. The DRV425 flux gate sensor is limited to 47kHz. The DRV421 is limited by the core of the transformer and the output difference amplifier of 2MHz. I am not sure of the frequency…
Hello Siva,
The maximum current for the devices in the Rshunt based will be determined by the gain and the Rshunt value. In the fluxgate based devices the mechanical construction will determine this but normally for the DRV425 use you would just use…
Hello Tim,
Currently we do not have a solution to excite an external hall sensor and provide an output. We do have the DRV425 that is a fluxgate that with a full scale to about 2mT. We also have a DRV5053 which is a hall sensor with analog output and…
Hello Divyanshu,
Once again, our apologies for the delay.
If you type vibration into the TI search engine, you can find several items that could assist you in building this product:

William,
The ADS1115 does not currently come in a non-magnetic packaging option. I checked, and there are only a handful of devices that come in a non-magnetic package option. They are mostly used in the medical imaging market for MRI applications…
Hello Manjunath,
Thank you certainly for posting to the forum.
Well this certainly requires making some fundamental design decisions. A CT could definitley transform the primary current to a smaller secondary current to sense with a shunt resistor…
The are many ways to measure current and Texas Instruments has a diverse portfolio to do exactly that!
Here are a few links to get you started measuring current with TI products:
If you don't know where to start with your current measurement design…
Hello Zhang,

I have uploaded a copy of the design document for TIDA-00463. I am not sure why the page is not appearing for you, you may want to discuss this separately with the web support team.
Note that this design does not use the…
Hello Idan,
My recommendation is to either use low-side sensing or indirect sensing (e.g. fluxgate/hall-effect sensors). While you could use the AMC1100 for a high-side measurement with 300V common-mode, the device would get damaged when the inputs…
Hey Saravanan,
This can be a difficult design to accomplish unless you can determine and limit some design considerations.
You should determine how much shunt resistor power dissipation you could allow over whole current range. Also how much error…
