Wcd9341 - Datasheet

The WCD9341 maintains superior dynamic range and THD+N compared to later models, though newer versions have improved power efficiency.

Standardized MIPI SoundWire digital interface used to communicate with the host processor for control and data. wcd9341 datasheet

Supports multiple differential analogue microphone inputs and digital microphone (DMIC) channels. The WCD9341 maintains superior dynamic range and THD+N

The WCD9341 is a designed for premium smartphones and portable devices. It represents Qualcomm’s move toward native DSD support and 32-bit/384 kHz playback before the industry shifted to integrated Aqstic codecs (WCD9380/90 series). wcd9341 datasheet
