Wcd9341 Datasheet [better] (2026)

The WCD9341 was widely adopted in the premium smartphone market between 2017 and 2019. It was most notably found in devices utilizing the platform (e.g., Google Pixel 3, OnePlus 6, Samsung Galaxy S9/S9+ in certain regions) and the Snapdragon 855 platform.

8.5/10 – excellent for its era, but showing its age in power efficiency and register complexity.

The WCD9341 is engineered to meet ultra-low distortion and high dynamic range standards required for high-resolution audio certification. Key Performance Metrics Up to 130 dB wcd9341 datasheet

The WCD9341 is typically offered in the WCD-9341-0-154WLPSP series of packages, with different suffix options:

This technical guide breaks down the core architecture, pin configurations, electrical specifications, and implementation strategies typically found within the WCD9341 documentation. 1. Overview and Key Features The WCD9341 was widely adopted in the premium

The WCD9341 is a low-power, high-performance audio codec that supports a wide range of audio interfaces, including I2S, TDM, and PDM. It is designed to meet the stringent requirements of mobile and portable devices, such as smartphones, tablets, and laptops. The chip's small form factor, low power consumption, and advanced feature set make it an ideal choice for designers looking to add high-quality audio capabilities to their products.

The internal architecture of the WCD9341 is divided into three primary functional domains: the digital processing core, the analog front-end, and the power management system. The WCD9341 is engineered to meet ultra-low distortion
