NAME
FUNCTION
3—
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 VLOGIC. On
power-up, the MAX5457 is in volume-control mode.
4—
MODE_IND
Volume-Control/Balance-Control Mode Indicator Open-Drain Output. Connect to
an LED through a resistor to VLOGIC. 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.
5
H0
Potentiometer 0 High Terminal. H0 and L0 terminals can be reversed.
6
L0
Potentiometer 0 Low Terminal. L0 and H0 terminals can be reversed.
7
W0
Potentiometer 0 Wiper Terminal
88
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.
99
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 VLOGIC.
10
W1
Potentiometer 1 Wiper Terminal
11
L1
Potentiometer 1 Low Terminal. L1 and H1 terminals can be reversed.
12
H1
Potentiometer 1 High Terminal. H1 and L1 terminals can be reversed.
13
VSS
Negative Power Supply. Bypass with 0.1F to ground.
14
GND
Ground
15
VLOGIC
Digital Logic Power Supply. Bypass with 0.1F to ground.
16
VDD
Analog Power Supply. Bypass with 0.1F to ground.
1—
DN/BAL0
Downward Volume/Channel 0 Balance-Control Input. In volume mode, pressing
DN/BAL0 moves both wipers towards the L terminals. In balance mode, pressing
DN/BAL0 moves the balance towards channel 0. DN/BAL0 is internally pulled up with
50k
to VLOGIC.
2—
UP/BAL1
Upward Volume/Channel 1 Balance-Control Input. In volume mode, pressing UP/BAL1
moves both wipers towards the H terminals. In balance mode, pressing UP/BAL1
moves the balance towards channel 1. UP/BAL1 is internally pulled up with 50k
to
VLOGIC.
—3
BAL1
Channel 1 Balance-Control Input. Pressing BAL1 moves the balance towards channel
1. BAL1 is internally pulled up with 50k
to VLOGIC.
—4
BAL0
Channel 0 Balance-Control Input. Pressing BAL0 moves the balance towards channel
0. BAL0 is internally pulled up with 50k
to VLOGIC.
—1
VOLDN
Downward Volume-Control Input. Pressing VOLDN moves both wipers towards
the L terminals. VOLDN is internally pulled up with 50k
to VLOGIC.
—2
VOLUP
Upward Volume-Control Input. Pressing VOLUP moves both wipers towards the
H terminals. VOLUP is internally pulled up with 50k
to VLOGIC.
