M
wiper changes position, the second wiper has 126ms
to change or it changes automatically.
Power-On Reset
The power-on comparators monitor (V
DD
- V
SS
) and
(V
LOGIC
- GND). A power-on reset is initiated when
either of the supplies is brought back to the normal
operating voltage. The power-on reset feature sets both
wipers to -12dB. The wipers initially wake up in mute
mode (-90dB) and move to the -12dB position when
V
H
= V
L
to eliminate clicks and pops during power-up.
With DC inputs at V
H
and V
L
, the wipers move after
exceeding the timeout period. A power-on reset places
the MAX5486 in volume-control mode.
Shutdown (
SHDN
)
Upon entering shutdown, the MAX5486 stores the last
wiper settings. The wipers move to the L_ end of the
resistor string when V
H
= V
L
to eliminate clicks and
pops during shutdown. With DC inputs at V
H
and V
L
,
the wipers move after exceeding the timeout period.
Exiting shutdown restores the wipers to their previous
settings. Shutdown also turns off all the LED indicators
to save power.
Mute Function (
MUTE
)
The MAX5486 features a mute function input,
MUTE
.
Successive low pulses on
MUTE
toggle its setting.
Activating the mute function forces both wipers to maxi-
mum attenuation (-90dB typ). Deactivating the mute
function returns the wipers to their previous settings.
MUTE
is internally pulled high with a resistor to V
LOGIC
.
When both wipers are in the tap 31 position
(-62dB attenuation) further commands to lower the vol-
ume place the wipers in the mute position (see Table 1).
Mode Indicator (
MODEIND
)
The open-drain
MODEIND
indicates volume-control
mode or balance-control mode for the MAX5486.
Connect
MODEIND
to an LED with a series resistor to
V
LOGIC
. When the LED is on, the MAX5486 is in bal-
ance-control mode. When the LED is off, the MAX5486
is in volume-control mode. See the Mode Control
(
MODE
) section for more detail on switching between
modes.
Level Indicator LEDs
The MAX5486 includes five indicator LED drivers to dis-
play the current wiper settings in either volume or bal-
ance mode. The LED indicators are enabled by
connecting a 1M
Ω
resistor between LEDIND4 and
V
LOGIC
. Connect the LEDIND_ outputs to the LEDs and
to V
LOGIC
through a series resistor as shown in the
Typical Operating Circuit Connect LEDIND_ outputs to
GND when LED indicator drivers are not used.
In volume-control mode, all LEDs are off when the
wipers reach the highest attenuation levels (mute). All
LEDs are on at the lowest attenuation levels (0dB).
