OUTPUT CONTROL

This section controls the auto level control (ALC) of the
SSM2380.
Figure 11. Output Control Section of
ALC Control 1 (Register R3)
This is associated with Control Register R3. This section allows
the user to control the release time and attack time of the
SSM2380.
ALC Control 2 (Register R4)
This is associated with Control Register R4. This section allows
the user to enable ALC operation, to set the compressor opera-
tion mode (light to heavy compression and limiting), to set the
limiter level, and to set the limiter mode.
There are two limiter modes: fixed power and supply tracking.
Fixed power mode sets the output limiter level to a fixed value,
independent of the power supply rail. Supply tracking mode
sets the limiter as a percentage of SPKVDD.
Note that if the user intends to change the gain setting registers,
R0 or R1, the user must toggle the ALC Enable check box to
allow the new gain settings to take effect.
