Stereo Audio Taper Potentiometers

with Pushbutton Interface

General Description

Features

The MAX5456/MAX5457 dual, logarithmic taper digital

potentiometers feature a simple pushbutton interface

that controls volume and balance in audio applications.

Each potentiometer has 32 tap points and replaces

mechanical potentiometers. Refer to the MAX5408–

MAX5411 data sheet for SPI™ versions of the MAX5456/

MAX5457.

♦ SmartWiper Control Provides Accelerated Wiper

Motion

♦ Debounced Pushbutton Interface with Internal

Pullup Resistors

♦ Logarithmic Taper with 2dB Steps Between Taps

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

Operation

Use the MAX5456/MAX5457 digital inputs with momen-

tary contact single-pole/single-throw (SPST) pushbutton

switches. Each input includes internal debounce cir-

cuitry and a 50k pullup resistor.

♦ Low 0.5µA Standbꢀ Supplꢀ Current

♦ Clickless Switching

♦ 10k End-to-End Fixed Resistance Value

♦ Mute Function to -90dB (tꢀp)

The MAX5456/MAX5457 advance the wiper setting once

per button push. Maxim’s proprietary SmartWiper™ con-

trol eliminates the need for a microcomputer 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 per second thereafter.

♦ Power-On Reset to -12dB Wiper Position

♦ 32 Tap Positions for Each Wiper

♦ Small 16-Pin QSOP/TQFN Packages

The MAX5456/MAX5457 provide temperature coeffi-

cients of 50ppm/°C end-to-end and 5ppm/°C ratiomet-

ric and a nominal resistance of 10k per potentiometer.

An integrated click/pop suppression feature minimizes

the audible noise generated by wiper transitions. The

typical total harmonic distortion plus noise (THD+N) for

these devices is 0.01%.

The MAX5457 features a 3-button interface with a

MODE input that toggles between volume- and balance-

control modes. An LED output indicates volume or bal-

ance mode. The MAX5456 features a 4-button interface

with separate inputs for up and down volume controls

and left and right balance controls.
