General Description
The MAX5406 stereo audio processor provides a com-
plete audio solution with volume, balance, bass, and
treble controls. It features dual 32-tap logarithmic
potentiometers for volume control, dual potentiometers
for balance control, and linear digital potentiometers for
tone control. A simple debounced pushbutton interface
controls all functions. The MAX5406 advances the
wiper setting once per button push. Maxim’s propri-
etary SmartWiper control eliminates the need for a
microcontroller (C) to increase the wiper transition
rate. Holding the control input low for more than 1s
advances the wiper at a rate of 4Hz for 4s and 16Hz
thereafter. An integrated click/pop suppression feature
eliminates the audible noise generated by the wiper’s
movements.
The MAX5406 provides a subwoofer output that inter-
nally combines the left and right channels. An external
filter capacitor allows for a customized cut-off frequen-
cy for the subwoofer output. A bass-boost mode
enhances the low-frequency response of the left and
right channels. An integrated bias amplifier generates
the required (VDD + VSS) / 2 bias voltage, eliminating
the need for external op amps for unipolar operation.
The MAX5406 also features ambience control to
enhance the separation of the left- and right-channel
outputs for headphones and desktop speakers sys-
tems, and a pseudostereo feature that approximates
stereo sound from a monophonic signal.
The MAX5406 is available in a 7mm x 7mm, 48-pin
TQFN package and in a 48-pin TSSOP package and is
specified over the extended (-40°C to +85°C) tempera-
ture range.
