Digital High Pass Filter
The ADC has a digital high pass filter for DC offset cancellation. The cut-off frequency of the HPF is 1.25Hz
(@fs=8kHz) and scales with sampling rate (fs).
MIC Gain Amplifier
The AK4632 has a Gain Amplifier for Microphone input. This gain is 0dB, +20dB, +26dB or +32dB, selected by the
MGAIN1-0 bit. The typical input impedance is 30k
.

MIC Power
The MPI pin supplies power for the Microphone. This output voltage is typically 0.75 x AVDD and the load resistance is
minimum 2k
. No capacitor must not be connected directly to MPI pin. (See Figure 30)
