Audio Processor with Pushbutton Interface

General Description

Features

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.

♦ Audio Processor Including All Op Amps and Pots

for Volume, Balance, Mute, Bass, Treble,

Ambience, Pseudostereo, and Subwoofer

♦ 32-Tap Volume Control (2dB Steps)

♦ Small, 7mm x 7mm, 48-Pin TQFN and 48-Pin

TSSOP Packages

♦ Single +2.7V to +5.5V or Dual 2.7V Supplꢀ

Operation

♦ Clickless Switching and Control

♦ Mute Function to < -90dB (tꢀp)

♦ Channel Isolation > -70dB (tꢀp)

♦ Two Sets of Single-Ended or Differential Stereo

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

♦ Shutdown Stores All Control Settings

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.
