The WCD9341 is controlled via I²C (up to 400 kHz) or SLIMbus. Key register groups:
In a small, cluttered workshop nestled in the heart of a bustling city, a young engineer named Emma stumbled upon an obscure reference to the WCD9341 datasheet. She had been searching for an elusive part to complete her pet project, a retro-style gaming console. As she poured over the cryptic documentation, Emma became increasingly fascinated by the WCD9341's specifications. wcd9341 datasheet
The is an advanced High-Fidelity (Hi-Fi) audio codec developed by Qualcomm , operating under their Aqstic brand umbrella. Its primary function is to convert digital audio streams into high-quality analog signals (DAC) and vice-versa (ADC). Designed specifically to be paired with high-end Snapdragon mobile processors, the WCD9341 was built to rival even dedicated, branded audiophile DACs by offering objectively better objective measurements and performance. 2. Key Specifications and Technical Highlights The WCD9341 is controlled via I²C (up to
The WCD9341 is housed in a package with either 107-ball or 110-ball configuration depending on the revision. As she poured over the cryptic documentation, Emma

Qualcomm WCD9341 is a high-performance, standalone audio codec that has powered the audio systems of numerous flagship smartphones and other premium mobile devices. Often paired with the powerful Snapdragon 845 and 835 mobile platforms, this codec is a hallmark of high-resolution audio in the Android ecosystem. This article serves as a comprehensive reference for the WCD9341, compiling its key specifications, architectural features, and design considerations from various technical documents and public sources.
A great codec doesn't just play back audio; it has to capture it perfectly. The WCD9341 includes powerful Analog-to-Digital Converters (ADCs) that make features like High Dynamic Range (HDR) audio recording and ultra-quiet voice dictation possible. This is highly beneficial for multi-mic background noise cancellation and high-fidelity video recording in loud environments. 4. Power Efficiency & Management
