USB Sound Card/Adapters

[Desmond74]

Hi all. I am planning to build an impedance measurement rig, and I am looking for a USB external sound card / adapters which provide 2 inputs or stereo microphone inputs. Most of those available are only one input or mono microphone input.
Any recommendation on any model or brand?
I only found this which is clearly spec

ADA-15 USB - HQ MINI AUDIO​

ADA-17 USB - HQ MINI AUDIO​

Thanks in advance guys.
