the device.
Active-Low Downward Volume/Balance Control. Press DN/BALR to decrease the volume in volume
mode and move balance to the right in balance mode. DN/BALR is internally pulled high with a
resistor to V
Active-Low Upward Volume/Balance Control. Press UP/BALL to increase the volume in volume mode
and move balance to the left in balance mode. UP/BALL is internally pulled high with a resistor to
V
Active-Low Mute Input. Pull MUTE low to toggle the wiper between the mute setting (see Table 1) and
the current setting. MUTE is internally pulled up to V
Active-Low Volume/Balance Control Input. Each high-to-low transition on MODE toggles between the
volume and balance modes. MODE is pulled high internally with a resistor to V
the MAX5486 is in volume control mode.
Active-Low Shutdown Input. Drive SHDN low to place the device in shutdown mode. In shutdown
mode, the MAX5486 stores the last wiper settings. The wipers move to the L_ end of the resistor
string. Terminating the shutdown mode restores the wipers to the previous settings.
Internally connected. Leave unconnected.
