MIC Device Connection Example
Figure 9 and Figure 10 show the connection example of MIC Device. In this case, a mono microphone is connected to
LIN pin the AK5355. Unused RIN pin can be open. The power supply for the microphone is provided via 4.4k
(2.2k
+ 2.2k
) from analog power supply. The power supply noise provided to the microphone should be care because the
microphone gain is usually high, around 40dB. In Figure 9, 1
st
order LPF by 2.2k
and 10
μ
F is inserted between the
power supply and the microphone.
The AK5355 has a gain of +15dB in analog stage. However, as the usual application needs a gain of around 40dB or
50dB, the shortage of gain, 25dB or 35dB, should be covered by digital processing like DSP.
The total S/N in each gain level is shown in Table 3
