Output Digital volume (Manual mode)
When ADCPF bit =
“
0
”
and ALC2 bit =
“
0
”
, ALC block become an output digital volume (manual mode). The digital
volume’s gain is set by OVOL7-0 bits as shown in Table 21. The OVOL7-0 bits value are reflected to this output volume
at zero cross or zero cross time out. The zero crossing timeout period is set by ZTM1-0 bits.

Table 21. Output Digital Volume Setting
When writing to the OVOL7-0 bits continually, the control register should be written by an interval more than zero
crossing timeout. If not, zero crossing counter could be reset at each time and volume is not be changed. However, It
could be ignored when writing a same register value as the last time. At this time, zero crossing counter has not been reset,
so it should be written by an interval less than zero crossing timeout.
Output Digital Volume2
AK4633 has 4 steps output volume in addition to the volume setting by OVOL7-0 bits. This volume is set by DATT1-0
bits as shown in Table 22.
