Hi ADI colleague
the MIC output specification:
→The MIC output：
Mic phantom power supply requirements:
- Supply voltage: 8.5 +/- 0.5V
Mic output characteristics:
- Output type: Unbalanced output
- Maximum AC signal output voltage: 2 Vrms
- Output impedance: 1kohm
If the MIC output is unbalanced output, ADAU1977 cannot support diagnostic fuction.
Is my understanding right?
Thank you for you support!
