WCD9341 Datasheet: A Comprehensive Guide to Qualcomm’s Audiophile-Grade Audio Codec

Introduction

In the world of mobile and embedded audio, the codec is the heart of the listening experience. While many consumers focus on DACs (Digital-to-Analog Converters) and amplifiers, the true magic happens inside a highly integrated audio codec. One such legendary component is the Qualcomm WCD9341.

The representative, a man named Mr. Li, explained that the WCD9341 was indeed still in production, albeit in limited quantities. He offered Emma a sample, provided she could prove her legitimacy as a legitimate engineer or project developer. Emma was thrilled and quickly provided the necessary documentation. | Parameter | Condition | Min | Typ

Native DSD Support: Provides native decoding for DSD64 and DSD128 (Direct Stream Digital), which was previously exclusive to SACDs and high-end portable players. Emma was thrilled and quickly provided the necessary

mobile platform. It is widely used in flagship devices like the Samsung Galaxy S8 Key Specifications Audio Quality : Supports playback of up to 384 kHz / 32-bit PCM audio and native DSD (Direct Stream Digital) Performance

Important Warning from Section 4.2: The internal LDOs require a minimum load current of 10 mA to maintain regulation. Floating the output is not allowed.
