Of course there are, any mixer that comes with an audio interface is what you are looking for.
But they can be pricey ! You might be better off having an analog mixer and a separate audio interface. but if you can't and actually need to go mixer + interface, a walk to your nearest music store could find you something that fits your needs.

The mixer I'm interested in (see comments) has stereo output, which means it can put out sound through two channels. This means you individually send input to one of the channels. For example, if you are recording with four microphones, you can have two left (1) and two right (2) or one left and the rest right.
