Before you power up the chip, consult the "Absolute Maximum Ratings" table in the WCD9341 datasheet. Exceeding these values will destroy the IC:
The official errata for the WCD9341 (Document #Q-8732-8) lists several known issues:
When designing a circuit board with the WCD9341, the application notes section of the datasheet details exact external layout practices. Layout Guidelines wcd9341 datasheet
Real-time monitoring of voltage and current (IV sensing) to prevent thermal and mechanical speaker damage. 3. Pin Configuration and Package Details
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. Before you power up the chip, consult the
Verify that the Master Clock (MCLK) provided by the PMIC or SoC is stable and jitter-free; unstable clocks will cause audible popping, clicking, or synchronization drift.
