MODE
Volume/Balance Control. Each transition from high to low toggles between volume
and balance modes.
MODE
is pulled high internally with a 50k
resistor to V
LOGIC
.
On power-up, the MAX5457 is in volume-control mode.

MODE_IND
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 MAX5457 is in
balance-control mode. When the LED is off, the MAX5457 is in volume-control
mode. See the
Mode Indicator, MODE_IND
section for more detail.

SHDN
Active-Low Shutdown Input. In shutdown mode, the MAX5456/MAX5457 store the
last wiper settings. The wipers move to the L end of the resistor string, and the H
end of the resistor string disconnects from the signal input. Terminating shutdown
mode restores the wipers to their previous settings.

MUTE
Mute Input. When
MUTE
is low, the wiper goes to the highest attenuation setting
(see Table 1).
MUTE
is internally pulled up with 50k
to V
LOGIC
.
Potentiometer 1 Wiper Terminal
Potentiometer 1 Low Terminal. L1 and H1 terminals can be reversed.
Potentiometer 1 High Terminal. H1 and L1 terminals can be reversed.
Negative Power Supply. Bypass with 0.1μF to ground.
Ground
Digital Logic Power Supply. Bypass with 0.1μF to ground.
Analog Power Supply. Bypass with 0.1μF to ground.
