The maximum output amplitude threshold (VTH) during the
limiting mode can be changed from 90% to 45% of VDD by
having an external resistor, RTH, between the VTH pin and GND.
Shorting the VTH pin to GND sets VTH to 90% of VDD. Leaving
the VTH pin unconnected sets VTH to 45% of VDD. The relation
of RTH to VTH is shown by the following equation:

ENABLE/DISABLING ALC
where RSP is the speaker impedance.
The ALC function is enabled when the ALC_EN pin is set to
VDD. The ACL function can be enabled and disabled during
amplifier operation. As a result of enabling ALC, ISY increases
by 100 μA and there is less than 50 μA source current from the
VTH pin to GND via RTH. When ALC is disabled, the source
current is 0 μA and the VTH pin is tied to GND.
Figure 43 shows the relationship between the RTH value and
VTH. Figure 44 shows the relationship between the maximum
output power and the RTH value.
