MAX5456/MAX5457
Click/Pop Suppression
The click/pop suppression feature reduces the audible
noise (clicks and pops) that result from wiper transitions.
The MAX5456/MAX5457 minimize this noise by allowing
the wiper position changes only when VH_ = VL_. Thus,
the wiper changes position only when the voltage at L_ is
the same as the voltage at the corresponding H_. Each
wiper has its own suppression and timeout circuitry (see
Figure 5a). The MAX5456/MAX5457 change wiper posi-
tion after 32ms or when VH_ = VL, whichever occurs first
(see Figure 5b).
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.
Power-On Reset
The power-on comparators monitor VDD - VSS and
VLOGIC - GND. A power-on reset is initiated when either
of the supplies is brought back to normal operating
voltage. The power-on-reset feature sets both wipers to
-12dB. Power-on reset places the MAX5457 in volume-
control mode.
