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
50kΩ to V
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 50kΩ to V
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 50kΩ to V
Active-Low Left Balance Control Input. Press BALL to move the balance towards the left channel.
BALL is internally pulled up with 50kΩ to V
Active-Low Right Balance Control Input. Press BALR to move the balance towards the right channel.
BALR is internally pulled up with 50kΩ to V
Digital Ground
Digital Power-Supply Input. Bypass with 0.1µF to DGND.
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.
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 50kΩ to
V
state between flat and full bass boost on each button press.
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 50kΩ to
V
state between flat and full bass boost on each button press.
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
50kΩ to V

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.
