Balance Control
In balance-control mode, the MAX5440 adjusts the bal-
ance between channel 0 and channel 1 while maintain-
ing the set volume. For example, if the volume of
channel 0 equals the volume of channel 1, forcing the
balance towards channel 1 increases the attenuation of
channel 0 (Figure 3a). If channel 1 is at a higher attenu-
ation than channel 0, adjusting the balance to channel
1 moves channel 1’s wiper up to the same wiper posi-
tion as channel 0 before it was attenuated (Figure 3b).
Click-and-Pop Suppression
The click-and-pop suppression feature reduces the
audible noise (clicks and pops) that results from wiper
transitions. The MAX5440 minimizes this noise by allow-
ing the wiper to change position only when VH = VL.
Each wiper has its own suppression and timeout cir-
cuitry. The MAX5440 changes wiper position when VH
= VL, or after 32ms, whichever occurs first (see Figures
4a and 4b).
The suppression circuitry monitors left and right chan-
nels separately. In volume-control mode, when the first
wiper changes position, the second wiper has 32ms to
change or it will be forced to change.
