Note 9. INT_MIC_L, INT_MIC_R, EXT_MIC_L and EXT_MIC_R pins
Note 10. Maximum output voltage is typically (MVDD-1.3) V.
Note 11. When output pin drives some capacitive load, some resistor should be added in series between output pin and
Note 12. These values are measured via the following path. EQ-Amp and HPF-Amp are a unity gain buffer.
Note 13. In case of the following path, output noise voltage is suitable value for -59.4dB (typ) and -55.4dBV (min).
Note 14. In the following path, if analog input signal is –70dBV (Then analog output level is –10.5dBV at LINEOUT),

MIC Block (Gain: +26dB, Input from INT_MIC_L/INT_MIC_R pins)
DAC+LINEOUT (Gain: +7.5dB, Measured via LOUT1/ROUT1 pins)
output noise voltage except the fundamental wave is suitable value for 58.4dBV(typ.) and –54.4dBV(min.).
Because it is not possible that each block of IPGA, ADC, DAC and LINEOUT output a distortion when the small
signal level is input.
