NAME
FUNCTION

13
MUTE
Active-Low Mute Control Input. Toggles state between muted and not muted. When in the mute
state, all wipers are moved to the low end of the volume potentiometers. The last state is restored
when MUTE is toggled again. The power-on state is not muted. MUTE is internally pulled up with
50k
Ω to VLOGIC.
20
14
VOLDN
Active-Low Downward Volume Control Input. Press VOLDN to decrease the volume. This
simultaneously moves left and right volume wipers towards higher attenuation. VOLDN is internally
pulled up with 50k
Ω to VLOGIC.
21
15
VOLUP
Active-Low Upward Volume Control Input. Press VOLUP to increase the volume. This simultaneously
moves the left and right volume wipers towards the the lower attenuation. VOLUP is internally pulled
up with 50k
Ω to VLOGIC.
22
16
BALL
Active-Low Left Balance Control Input. Press BALL to move the balance towards the left channel.
BALL is internally pulled up with 50k
Ω to VLOGIC.
23
17
BALR
Active-Low Right Balance Control Input. Press BALR to move the balance towards the right channel.
BALR is internally pulled up with 50k
Ω to VLOGIC.

18
DGND
Digital Ground
25
19
VLOGIC
Digital Power-Supply Input. Bypass with 0.1F to DGND.
26
20
SHDN
Active-Low Shutdown Control Input. In shutdown mode, the MAX5406 stores every wiper’s last
position. Each wiper moves to the highest attenuation level of its corresponding potentiometer.
Terminating shutdown mode restores every wiper to its previous setting. In shutdown, the MAX5406
does not acknowledge any pushbutton command.
27
21
BASSDN
Active-Low Downward Bass Control Input. Press BASSDN to decrease bass boost. Bass boost
emphasizes the signal’s low-frequency components. BASSDN is internally pulled up with 50k
Ω to
VLOGIC. To implement a bass-boost button, connect BASSDN to BASSUP. Presses then toggle the
state between flat and full bass boost on each button press.
28
22
BASSUP
Active-Low Upward Bass Control Input. Press BASSUP to increase bass boost. Bass boost
emphasizes the signal’s low frequency components. BASSUP is internally pulled up with 50k
Ω to
VLOGIC. To implement a bass-boost button, connect BASSUP to BASSDN. Presses then toggle the
state between flat and full bass boost on each button press.
29
23
TREBDN
Active-Low Downward Treble Control Input. Press TREBDN to decrease the treble boost. Treble
boost emphasizes the signal’s high-frequency components. TREBDN is internally pulled up with
50k
Ω to VLOGIC.
30
24
TREBUP
Active-Low Upward Treble Control Input. Press TREBUP to increase the treble boost. Treble boost
emphasizes the signal’s high-frequency components. TREBUP is internally pulled up with 50k
Ω to VLOGIC.
31
25
AMB
Active-Low Ambience Switch Control Input. Drive AMB low to toggle on/off the ambience function.
AMB is internally pulled up with 50k
Ω to VLOGIC.
33
27
CRSN
Subwoofer Right-Channel Highpass Filter Capacitor Negative Terminal. Connect a capacitor
between CRSN and CRSP to set the highpass cutoff frequency at SUBOUT. See the Subwoofer
Ouput section for more details.
34
28
CRSP
Subwoofer Right-Channel Highpass Filter Capacitor Positive Terminal. Connect a capacitor between
CRSP and CRSN to set the highpass cutoff frequency at SUBOUT. See the Subwoofer Ouput
section for more details.
