Today, we continue our series on successive approximation register (SAR) analog-to-digital converters (ADCs) input types.

You are now comparing the difference between the terms: </p> <p>a1(VDIFF) for single-ended vs. c1(VDIFF/2) = a1(VDIFF/2) + b1(VDIFF/2) for differential inputs. </p> <p>So its a comparison between a1 &nbsp;vs. (a1+b1)/2.Amit</p> <img src="https://e2e.ti.com/aggbug?PostID=666513&AppID=930&AppType=Weblog&ContentType=0" width="1" height="1">https://e2e.ti.com/blogs_/archives/b/precisionhub/posts/performance-comparison-between-sar-adc-input-types-part-2Sat, 25 Oct 2014 13:13:24 GMTcb01d8b2-d089-468d-babb-77d1d8683490:ac183784-c697-488e-a3f6-e2b82e920c25Dan Tooth0<p>the even harmonics cancel - do the odd harmonics increase?</p> <img src="https://e2e.ti.com/aggbug?PostID=666513&AppID=930&AppType=Weblog&ContentType=0" width="1" height="1">
