AMC130M03: ADC Inquiry

Hi Nikhil,

I would be happy to find you a recommendation. What is your application? This may help me think of other parts to offer as well. 

The closest device to those specs would be the AMC130M03. It is a 16-bit isolated ADC that features galvanic isolation, however, it only has three input channels. Please note our devices only go up to four input channels. 

Feel free to check out our comparison page here too:

Please let me know if I can answer any more questions. 

Best regards,

Hii Eva,

I want to use an 16 bit isolated ADC for Temperature Sensing. As I am receiving Data from 12 different Temp sensors (PT100), hence required 12 input channels. But as you mentioned your devices only go up to four input channels, So I have to use 3-4 nos. ADC for my application.

It would be very helpful if you could provide me the P/N for the same.

Thanks

Nikhil

Hi Nikhil,

I understand. One solution could be using multiple of our ADCs, like the one I mentioned, and synchronizing them. If you wanted to use our four-input channel device we have the AMC1210, however, this is a modulator so it might require more stages. 

Otherwise, you could use an ADS part and incorporate discrete isolation. These parts go up to 8 channels but do not include galvanic isolation like you are looking for.

Please let me know what you think!

Best regards,

Eva
