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.
