[sdiy] Quantizer DAC or PWM?

I’m working on developing a quantizer module for eurorack. I made a previous version using a PIC chip with a DAC which I abandoned during the chip shortage.
Now I’m looking at taking up the project again but possibly with an esp32-s3 chip instead. This chip only has PWM, though.

Question is whether PWM with smoothing circuit is it accurate enough for a quantizer? Does anyone have smoothing circuit to recommend?
Or is a DAC the better option?
