Wcd9341 Datasheet

. It is widely used in professional repair for smartphones like the Samsung Galaxy S8, Note 8, and Note 9

The uses a dense ball grid grid layout. Due to intellectual property regulations, full pin-level mappings are heavily protected under strict vendor NDAs. However, standard system integrations group these 154 pins into distinct functional blocks:

The WCD9341 datasheet reveals a wealth of features that make this audio codec chip stand out from the competition. Some of the key features include: wcd9341 datasheet

Optimized to prevent premature battery drain, crucial for high-resolution audio streaming.

The WCD9341 is part of Qualcomm's Aqstic series. While succeeded by newer codecs like the WCD9370 and WCD9375, its specifications remain impressive. A comparison highlights this: However, standard system integrations group these 154 pins

and extremely low Total Harmonic Distortion plus Noise (THD+N). Voice Features

Differential microphone traces must be routed with matched lengths to maintain high Common Mode Rejection Ratio (CMRR). Technical Support and Sourcing Datasheets While succeeded by newer codecs like the WCD9370
