Figure 1. THD+N vs. Input Level
Figure 2. THD+N vs. Input Frequency (Input Level = -1dBFS), C7: Ceramic Condenser
In this case, a ceramic condenser is used as C7 between MICOUT pin as AIN pin on the AKD4632-A.As the performance of
Ceramic condenser is not so good about low frequency signal. Refer to Figure 3 about the performance of AK4632.
