Procurement Notes
Verify the specific suffix 'YG' corresponds to the 20-pin QFN package variant when ordering. Confirm that the application design accounts for the exposed thermal pad connection requirements specified in the datasheet. Ensure supply voltage ranges align with the recommended operating conditions for optimal performance.
Selection Notes
Select this component for portable applications requiring high efficiency and low noise without external output filters. Consider the 20-pin QFN package for better thermal dissipation compared to WLCSP options. Verify compatibility with host digital audio interfaces supporting I2S or PCM protocols within the specified sampling rate range.
Part Context
The NAU8315 series includes variants in 9-ball and 12-ball WLCSP packages alongside the 20-pin QFN version. The YG suffix specifically denotes the QFN package type. This family targets battery-powered devices where space constraints and power efficiency are critical design factors.
