Designing hardware with the CX31993 requires careful attention to trace routing, grounding strategies, and decoupling networks to maintain the chip's native 124 dB SNR.
A: The difference is substantial. While a typical smartphone's internal DAC may achieve only 60-70dB SNR with noticeable distortion, the CX31993 offers >128dB SNR and <0.0003% THD+N. This translates to a much cleaner, more detailed sound with a lower noise floor and significantly better resolution.
: Greater than 128dB , ensuring a very low noise floor. Dynamic Range (DNR) : Greater than 120dB . macOS / iOS / iPadOS: CoreAudio compliant
The chip operates directly off the USB VBUS supply voltage but utilizes internal low-dropout (LDO) regulators to generate clean analog rails, minimizing the impact of source power supply noise.
