Figure 21. Microphone Input
The AK4641 has the following functions for Mic Input.
(1) 1
st MIC Amplifier of 20dB gain that can be selected ON/OFF by “MGAIN” bit.
(2) 2
nd Amplifier that has PGA with ALC. This volume is controlled by “IPGA6-0” bit as Table 7.
While ALC is working, Master Clock must be present.
When Master Clock is not provided or PMMIC bit = “0”, it is invalid to write to “IPGA6-0”.
(3) Attenuator for stereo mixer. This volume is controlled by “ATTS2-0” bit as Table 8.
(4) Attenuator for mono mixer. This attenuator level is 4dB and this ON/OFF is controlled by “ATTM” bit.
