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 (µC) 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 (V

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.
