dear All,

is it possible to write ADC's data on a memory IC without need a micro-controller?

how can I do this?

Rasool,

I thing that you'll need some sort of basic microcontroller to get data out of the ADC and into a memory IC. I don't think there's a way around that.

how can MCUs interface with ADCs at data transfer rating of several MSPS?

Hi Rasool,

You need a processor capable of handling the output rate of the ADC. If you share which ADC you want to use, then maybe we can steer you in the right direction. Sometimes an FPGA or DSP is used that often have faster clock rates.

dear Bob Benjamin,

i don't had select the ADC yet. but i need an ADC with the bellowing characteristics:

sampling rate >= 3.3 MSPS

resolution >= 12 bits

channel: 1 is enough

best regards,

Rasool

Hi Rasool,

I would suggest you choose a device and the desired interface and then find a processor to support it. Most likely this will be a SAR ADC. There are some serial interface devices that can go up to 3MHz, but you may need to have a device with a parallel interface.
