It's not quite that simple.
The GUS Classic only has a GF1 chip, which is a hardware mixing device, basically a RAM-based wavetable synthesizer.
It doesn't actually have a regular DAC at all (which also means it's poorly supported in Windows for example, which expects a simple mono or stereo DAC, where the GUS has to play sound through its synthesizer).
Best-case you get 16-bit 44 KHz out of the synthesizer. However, when you use more than 14 channels, the mixing rate goes down. It can do 32 channels maximum, at which point it is about 19 KHz.
Also, best-case you get 16-bit samples, but when the RAM gets full, samples may get reduced to 8-bit to fit them in memory.

I don't know of any games that use the GUS MAX DAC. It is also not used for SB emulation. SBOS uses the GF1 synth.
It can be used in Windows, and it's more compatible than using the GF1.
