Balance Control
In balance-control mode, the MAX5486 adjusts the bal-
ance between the right and left channels while main-
taining the set volume. For example, if the volume of the
right channel equals the volume of the left channel,
forcing the balance towards the left channel increases
the attenuation of the right channel (Figure 3a). If the
left channel is at a higher attenuation than the right
channel, adjusting the balance to the left channel
moves the left channel’s wiper up to the same wiper
position as the right channel 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 MAX5486 minimizes this noise by allow-
ing the wiper to change position only when V
H
= V
L
(zero crossing) or after the zero crossing timeout
(126ms). Each wiper has its own suppression and time-
out circuitry. The MAX5486 changes wiper position
when V
H
= V
L
, 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
