How to improve the sampling rate of Arduino due ADC?

I am now working on a project, which needs a cheap analog acquisition device with a sampling rate of no less than 5MHz. Before, I only used Arduino, and rarely operated the registers on Arduino. I hope to use Arduino due to complete it. I spent a lot of time researching and querying solutions, but it didn't succeed. I hope someone can help me.

Thank you very much for your reply. After your reminding, I have turned off my interrupt. It's really effective, but it's still far from enough. I think 12 digits are offline to ensure accuracy.,so It seems that I may have to find another way.

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
