If you provide more details about what specific information you need from the datasheet (e.g., pinout, I2C registers, electrical characteristics, or typical application circuit), I may be able to summarize public knowledge or help you locate an equivalent public document.
This is the most referenced section of the WCD9341 datasheet. Below are the characteristic values under typical conditions: V_AVDD = 1.8V, TA = 25°C, fs = 48 kHz.
Note: Native DSD requires the host processor (e.g., Snapdragon 855) to support DSD interface mode, which is a proprietary Qualcomm extension. wcd9341 datasheet
The is a highly integrated audio codec (COder-DECoder) developed by Qualcomm, typically paired with Snapdragon 845, 855, and 855+ mobile platforms. Unlike standard codecs that prioritize power efficiency over quality, the WCD9341 was designed to deliver "Hi-Fi" audio with native support for Direct Stream Digital (DSD) and high-resolution PCM streams.
The WCD9341 remains competitive due to its and higher line output voltage , which many newer codecs have removed to save battery. If you provide more details about what specific
The reveals a component that was far ahead of its time. With 122 dB SNR, native DSD, and a powerful Class-G amplifier, it set a benchmark that even some modern desktop DACs struggle to match. For hobbyists, repairing a classic LG or Xiaomi device, or designing a portable Hi-Fi player, understanding this datasheet is essential.
: High dynamic range of up to 123 dB , minimizing the gap between the loudest and quietest sounds for clearer detail. Note: Native DSD requires the host processor (e
