Enob calculation for SD ADC. Accuracy against conversion time

stanpodlisker — Mon, 25 Nov 2013 07:37:38 GMT

I'd like to evaluate the MKMxxZxxCxx5 for high accuracy of my measurement. So my questions are: 1. How to calculate the ENOB for their integrated SD ADC.What the dependency between ENOB,Sampling clock,and OSR. I need to estimate the design to conversion time against accuracy because the conversion time may be critical. 2. I need also to understand the SINAD and CMMR for Bandwidth up to 10 kHz of differential Analog inputs 3. Is the any DMA channel works with SD ADC

Hi Stan,

Sure, ADC can work with DMA.About your other question, I think you'd better to reference the datasheet.

I attach a application document that introduce how to configure ADC work with DMA and datasheet of K60.

Wish these can help you.

Best regards,
