Anything that increases your web presence is likely to positively impact your SEO. Ads increase your brand awareness. If these ads causes users to share your content on social media, organically link to your page, talk about about your brand, or search for your company on Google you SERP position is likely to go up.
But you shouldn't expect the links pointing to your site from ads to increase your rankings. Many ads add the rel="nofollow" tag so the backlink won't count. And Google has said that buying backlinks is a big no no. If you buy an ad to your site with a paid for backlink it's possible that you may get penalized for it if Google finds out. This is just something you have to think about.
As for advertising in general though, yes it will help your brand. And anything that helps your brand that is in line with Google Webmaster Guidelines is likely to increase your rankings.
