Hi TI Team
Is it possible to use the AMC3330 in combination with the ADS127L18 getting a final accuracy of +/-16bit (17bit)? Is it correct that I have to add a Differential to Single-Ended Output Conversion if I use this ADC with just a +5V supply?
Thank you in advance.

Hi Theo,
Can you provide some details about your system and use case? You could just use an AMC131M01 or AMC131M03, which are isolated ADC's with a SPI interface.
Thanks.
Hi Saleh
I figured it out by myself. There is an Excel Sheet provided by TI to calculate the accuracy. And it seems impossible to get it to 0.01% over a temperature of 0-60°C without sensing the temperature itself which we want to avoid.The other two devices you mentioned are interesting but they seem to end up with the same issue. We have a design with an isolated ADS127L21 + OPA2388 which should theoretically be capable of delivering the 0.01% over temperature.
Thanks for your help.
