NAME
FUNCTION
1
V
LOGIC
Digital Logic Power Supply. Bypass V
LOGIC
to ground with a 0.1μF capacitor as close as possible to
the device.
2
DN
/
BALR
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
LOGIC
.
3
UP
/
BALL
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
LOGIC
.
4
MUTE
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
LOGIC
with a resistor.
5
MODE
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
LOGIC
. On power-up,
the MAX5486 is in volume control mode.
6
SHDN
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.

LED Indicator Open-Drain Output 0–LED Indicator Open-Drain Output 4. Connect a 1M
Ω
resistor
from LEDIND4 to V
LOGIC
to enable these LED inductor drivers. LEDIND0–LEDIND4 form a bar graph
indication of the current volume or balance. In volume mode, all LEDs off indicate mute and all LEDs
on indicate maximum volume. In balanced mode, LED2 on indicates centered or balanced. Connect
LEDIND0–LEDIND4 to GND when LED indicator drivers are not used.

MODEIND
Active-Low Volume-Control/Balance-Control Mode-Indicator Open-Drain Output. Connect to an LED
through a resistor to V
LOGIC
. When the LED is on, the MAX5486 is in balance-control mode. When the
LED is off, the MAX5486 is in volume-control mode.
