The input stage accommodates multiple microphone configurations:
The WCD9341 is a high-performance audio codec chip that offers a range of features and benefits for audio applications. Its high-fidelity audio playback and recording capabilities, low power consumption, and flexible audio interfaces make it an attractive solution for device manufacturers.
Despite its high performance, the WCD9341 is designed with mobile battery life in mind: wcd9341 datasheet
The WCD9341 functions as the central hub for all analog and digital audio signals within a mobile system architecture. It bridges the application processor (typically a Qualcomm Snapdragon SoC) with the physical audio components of the device, such as microphones, speakers, and earpieces. Key Functional Blocks
