Volume Control
In volume-control mode, the MAX5440’s wipers move
simultaneously, maintaining the balance separation
between each wiper (Figure 2a).
When either wiper reaches the maximum tap position
(position closest to H_), further commands to increase
the volume are ignored. Balance separation is main-
tained in the maximum volume configuration (Figure 2b).
When either wiper reaches the minimum tap position
(position closest to L_), further commands to decrease
the volume adjust the other wiper until it also reaches
the minimum tap position (Figure 2c).
Increasing the volume from this minimum position
restores the original balance separation of the wipers
(Figure 2d).
When both wipers are in the tap 31 position (-62dB
attenuation), further decreasing rotations place the
wipers in the mute position (see Table 1). Rotating the
encoder to a lower attenuation or a pulse to MUTE
returns the wipers to tap 31.
