Features

  • a 3-button interface with a MODE input that toggles between volume- and balancecontrol 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 are available in 16-pin QSOP and 16-pin TQFN packages and are specified over the extended (-40°C to +85°C) temperature range. Features.
  • SmartWiper Control Provides Accelerated Wiper Motion.

19-3490; Rev 0; 11/04 www.DataSheet4U.com Stereo Audio Taper Potentiometers with Pushbutton Interface General Description 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.
