Wcd9341 Datasheet _verified_ Jun 2026
The is a high-tier, standalone hardware audio codec IC designed to deliver audiophile-grade high-fidelity (Hi-Fi) sound and power voice-activation capabilities. Launched alongside the Snapdragon 835 mobile platform, the WCD9341 acts as a dedicated audio hub featuring integrated analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and headphone amplifiers. This comprehensive technical article breaks down the WCD9341 specifications, pin architecture, performance metrics, and application logic typically detailed across official Qualcomm Aqstic documentation . Core Specifications & Performance Metrics
Supports multiple differential analogue microphone inputs and digital microphone (DMIC) channels.
The WCD9341 is targeted at high‑performance consumer electronics where audio quality is a key differentiator:
In real-world use, the WCD9341 is often paired with external amplifiers, such as the Cirrus Logic CS35L41 , to drive more demanding headphones. While it is a durable Qualcomm component, failures in older devices often manifest as no sound or microphone issues, requiring specialized chip replacement by technicians.
