Product Details

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.
Use the MAX5456/MAX5457 digital inputs with momentary contact single-pole/single-throw (SPST) pushbutton switches. Each input includes internal debounce circuitry and a 50kΩ pullup resistor.
The MAX5456/MAX5457 advance the wiper setting once per button push. Maxim's proprietary SmartWiper™ control 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.
The MAX5456/MAX5457 provide temperature coefficients of 50ppm/°C end-to-end and 5ppm/°C ratiometric and a nominal resistance of 10kΩ 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 an active-low MODE input that toggles between volume- and balance-control modes. An LED output indicates volume or balance mode. The MAX5456 features a 4-button interface with separate inputs for up and down volume controls and left and right balance controls.
The MAX5456/MAX5457 is available in a 16-pin QSOP packages and specified over the extended (-40°C to +85°C) temperature range.
