I am using an applications that requires at least 2 but possibly 3 differential ADC Inputs. The&nbsp;MK66FN2M0VLQ18 reference manual eludes to there being up to 4 differential ADC inputs but the MK66FN2M0VLQ18 datasheet&nbsp;&nbsp;has only 3 pins labels with DM marker and one is an overlap between the two diffent input channels, meaning I can at best only use one differential ADC input. Is this right or is there something I am missing like some of the single ended inputs can be used as well.</P><P></P><P>Thanks,</P><P>John</P></BODY></HTML> Mon, 23 Apr 2018 18:34:30 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/MK66FN2M0VLQ18-ADC-DIFF-Inputs/m-p/759364#M46268 johncooper 2018-04-23T18:34:30Z Re: MK66FN2M0VLQ18 ADC DIFF.
