Would you pls advise two specifications of the TPA6166?
1. Common mode input range of the TPA6166's microphone input signal on RING2 and SLEEVE.
2. Maximum output voltage of MOUTN
With 24dB gain and 2.6V mic bias, I got 1.3V DC bias on MOUTN, 2.4Vp signal on MOUTN. It means the maximum output swing is 0.848Vrms.
(1) 24dB Gain, the maximum input range is 0.848/15.84 ~= 50mV
(2) 12dB Gain, the maximum input range is 0.848/3.98 ~= 200mV
Is my calculation in line with the TPA6166's specification?
Thank you and Best regards,
