I got the gray one, which should have the TI PCM290. But I can check.
Edit.
It's a TI PCM2902. Here is the exact chip inside mine:

Glad you got one of the good ones.
It makes sense with the good performance you are getting .
EDIT :
Anybody considering one those should be weary of getting one of those not based on the TI chip . This is one technical review of that "bad" variant . Earlier less formal reviews point in the same direction .
See https://www.audiosciencereview.com/forum/inde … er-uca222.2036/
I believe that the review is wrong. It has since been pointed out that the CoolAudio V2902 chip found in UCA222 (as opposed to the BB branded PCM2902 chip in earlier UCA202s, which was also pruduced under license as far as I know) is actually the same IC produced under license by Behringer's CoolAudio brand. There is virtually no difference between the two units.
Datasheets:
PCM2902: https://www.ti.com/lit/ds/symlink/pcm2900.pdf
V2902: https://mediadl.musictribe.com/download/docum … 2_DATASHEET.pdf
They are 100% identical down to every single electrical characteristic - the datasheets are essentially copy pastes of one another. Moreover, even newer UCA202 units come with the CoolAudio V2902, not BB branded TI PCM2902 chips. The issue here is that the PCM2902A as well as the V2902 (which seems to be a licensed clone of) share the same issue of phase shift at higher frequencies. This was fixed in PCM2902B onwards, but for V2902 I have no idea - it does not even have revision markings, I believe. Regardless, UCA202 and UCA222 units can come with PCM2902A/B/C or V2902 - it's a gamble.
I haven't checked mine, but I will. Are they easy to open up?
