I need a microcontroller with an ADC sampling rate around 100Ksps at minimally 10bits, but finding any comparisons of different microcontrollers regarding sampling rates has proven to be quite difficult. The best source I have found is this white paper, where at page 12 there is a table of 5 uCs and their ADC sample rates... Not a very good source though.

If anyone could help me find an uC with higher sample rate, which could be ideally programmed without a special programming tool (like through an LPT port with avrdude, liko most of the AVR uCs or with an Arduino or with an USB to RS232 converter...), I would be most grateful.

Or please point me to some comparison tables, if there are any, and I can look for some uC that suits me.

    \$\begingroup\$ You say both 100Ksps, which is possible with a lot (most?) of the modern microcontrollers, and later you say 'with a higher sampling rate'? Manufacturers will provide parametric search and select within his own products only :) What other features do you need? My personal pet uC, the LPC1114, can do ~ 400Ksps. Software downbloading via a serial link. \$\endgroup\$ – Wouter van Ooijen Nov 11 '13 at 22:07
  • \$\begingroup\$ Damn I have been looking for something like a parametric search on the atmel.com site, but failed to find it... It's probably just too late already. \$\endgroup\$ – Matouš Vrba Nov 11 '13 at 22:22
  • \$\begingroup\$ Higher sampling rate was supposed to be higher than ATMega328 with 10bit resolution has, which is about 30KHz I think... forgot to mention. Well I found the parametric search already now, that I know it was there. Thanks for the comments. \$\endgroup\$ – Matouš Vrba Nov 11 '13 at 22:24

Are you maybe looking for something like the following? In no particular order:

Alas, the following distributors don't include a "sampling rate" column in their microcontroller parametric search tool (only a "number of ADCs" column). But they do have one in their ADC parametric search tool:

  • \$\begingroup\$ I don't know about the others, but the TI and Microchip parametric searches don't provide info that I can see regarding the RATE of A/D, just the number of ADC channels and how wide they are. \$\endgroup\$ – Scott Seidman Nov 12 '13 at 19:35
  • \$\begingroup\$ For reference, Atmel gives the recommended ADC clock rate range and ADC timing diagram, from which one can infer a sample rate (although they tend to list it in the Features subsection at the beginning of the ADC section in their datasheets regardless). \$\endgroup\$ – Ignacio Vazquez-Abrams Nov 12 '13 at 19:47
