• ADC: input range, THD+N, SNR, dynamic range, ENOB, sampling rates supported
• DAC: output drive, THD+N, SNR, dynamic range, output levels, load driving capability
• Headphone amp: output power into specified loads (e.g., 32 Ω), THD+N, PSRR
• Microphone bias specs, preamp gain range, input-referred noise, CMRR
• Channel counts and simultaneous ADC/DAC streams

Note:

The WCD9341 datasheet is explicit about grounding. Do not connect analog and digital grounds directly . The datasheet specifies a 0Ω resistor or ferrite bead between AGND and DGND near the chip. wcd9341 datasheet
