Qualcomm operates under a restricted documentation model. Complete datasheets, register maps, and software driver source codes for the WCD9341 are generally kept behind the Qualcomm CreatePoint portal. Original Equipment Manufacturers (OEMs) and authorized developers must sign a Non-Disclosure Agreement (NDA) to gain full access to the complete 500+ page technical reference manual. wcd9341 datasheet

ADC input impedance: 20 kΩ typical – watch out with high-Z MEMS mics (require external buffer).
