But for 99% of users, these are irrelevant. Cx31993 Datasheet Fix
If you are maintaining an internal datasheet for CX31993, append this errata: However, for months, the publicly available datasheets were
The has become a ubiquitous entry-level USB audio codec, found in dozens of affordable USB-C to 3.5mm dongles. However, for months, the publicly available datasheets were either incomplete, contained conflicting pinout information, or lacked critical register maps for I²C control. Enter the unofficial “CX31993 Datasheet Fix” – a community-sourced, annotated correction document that has quietly saved hundreds of hobbyist projects. Since this is a Class G chip, this
. Since this is a Class G chip, this isn't "switching noise" like a Class D amp. The best fix is implementing a low-pass filter
