circuit (see Figure 2). With zero-crossing enabled, the
MAX5408–MAX5411 change wiper position after 50ms
or when zero crossing is detected.
Power-On Reset
The power-on reset (POR) feature sets all the wipers to
the maximum attenuation (tap position 31, -62dB) at
power-up. If either VDD or VLOGIC is zero volts, a power-
on reset intiates when one of the supplies is brought
back to the operating voltage.
Mute Function
When mute is enabled, the wipers go to -90dB attenua-
tion. When mute is disabled, the wiper returns to its
position before mute was enabled. All wipers can be
muted simultaneously or independently.
Applications Information
Attenuation Control
Figure 3 shows the application of an attenuation control.
The op amps are connected in a follower configuration
with a fixed gain. The digitally controlled potentiometer
attenuates the input signal.
Stereo Volume Control
Figure 4 shows the application of stereo volume con-
trol using MAX5409/MAX5411. The op amps are con-
nected in a follower configuration with fixed gain. The
digitally controlled potentiometer attenuates the input
signals. The second wiper of each potentiometer con-
trols the signal amplitude at the rear set of speakers.
Daisy-Chaining
Figure 5 shows an application daisy-chaining the
serial-interfaces of the MAX5408–MAX5411. A single-
write command updates multiple devices from a single
digital port in this configuration (see Digital Serial
Interface section).
Gain Control
Figure 6 shows the application of a gain control.
Note: Muting the potentiometer creates unpredictable
behavior at the output of the op amp, and may seriously
degrade the performance of the op amp.
