MIC Gain Amplifier
The AK5701 has a gain amplifier for microphone input. The gain of MIC-Amp is selected by the MGAIN1-0 bits (
Table
20
). The typical input impedance is 60k
Ω
(typ)@MGAIN1-0 bits = “00” or 30k
Ω
(typ)@MGAIN1-0 bits = “01” or “10”.

MIC Power
When PMMP bit = “1”, the MPWR pin supplies power for the microphone. This output voltage is typically 0.75 x AVDD
and the load resistance is minimum 0.5k
Ω
. In case of using two sets of stereo mic, the load resistance is minimum 2k
Ω
for
each channel. Any capacitor must not be connected directly to the MPWR pin (
Figure 38
).
