NAME
FUNCTION
1VLOGIC
Digital Logic Power Supply. Bypass VLOGIC to ground with a 0.1F 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 VLOGIC.
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
VLOGIC.
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 VLOGIC 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 VLOGIC. 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.

N.C.
Internally connected. Leave unconnected.
8
HR
Potentiometer R High Terminal
9
LR
Potentiometer R Low Terminal
10
WR
Potentiometer R Wiper Buffered Output
11
BIAS
Midbias Voltage Output. VBIAS = (VDD + VSS) / 2; connect a 100pF capacitor from BIAS to VSS.
12
BIASCAP
Bias Generator Bypass. Connect a 1F filter capacitor from BIASCAP to VSS.
13
VDD
Analog Power Supply. Bypass VDD to ground with a 0.1F capacitor as close as possible to the
device.
14
VSS
Negative Power Supply. Bypass VSS to ground with a 0.1F capacitor as close as possible to the
device. Connect to GND for single supply operation.
15
WL
Potentiometer L Wiper Buffered Output
16
LL
Potentiometer L Low Terminal
17
HL
Potentiometer L High Terminal
18–22
LEDIND0–
LEDIND4
LED Indicator Open-Drain Output 0–LED Indicator Open-Drain Output 4. Connect a 1M
Ω resistor
from LEDIND4 to VLOGIC 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.
23
MODEIND
Active-Low Volume-Control/Balance-Control Mode-Indicator Open-Drain Output. Connect to an LED
through a resistor to VLOGIC. When the LED is on, the MAX5486 is in balance-control mode. When the
LED is off, the MAX5486 is in volume-control mode.

GND
Ground
