Wcd9341 Datasheet -

For system engineers and developers, the WCD9341 is well-supported in the Linux kernel:

Left/Right Headphone Jack Driver (Differential or Single-Ended) Analog Output Programmable bias voltage sources for electret microphones MAD_DATA / CLK Digital I/O

For hardware engineers and teardown specialists, the WCD9341 is a marvel of miniaturization. It is packaged in an ultra-compact, wafer-level picoscale package (WLCSP), which minimizes the physical footprint on the printed circuit board (PCB). This compact design is what allows modern, thin-bezel smartphones to pack studio-grade audio hardware without sacrificing space for larger batteries or camera modules.
