Hi all,

I am looking for device to interface 4 wired Pt100 on side and and I2C output on the other side (only one I2C o/p is enough). Our limitations are with smaller footprint. We have 3.3V,5V and 12V power supplies to power the device.

Currently I am working with the universal transducer interface device **broken link removed**

Has anyone used something like this for a project?

Thanks

Sn
 

I can't sure, you can get one IC with I2C communication, but you can consider LMP90100 which comes with SPI interface. Again it may take some spaces. For similar kind of application you can use some ADC where you can get ADC bit out which you have to convert it into temperature.
