MAX5486EUG+ Datasheet PDF - Maxim Integrated

The MAX5486EUG+ is a stereo volume control with pushbutton interface in 24 pin TSSOP package. The MAX5486 dual 40Kohm logarithmic taper volume control features a debounced pushbutton up/down interface that controls volume and balance in audio applications. Each potentiometer has 32 log-spaced tap points with a buffered wiper output to replace mechanical potentiometers. An integrated bias generator provides the required ((VDD + VSS)/2) bias voltage. It has a mode-indicator LED output and a five integrated LED drivers. Use the MAX5486 digital inputs with momentary contact SPST pushbutton switches. Each input includes internal debounced circuitry and a pull-up resistor to VLOGIC. The SmartWiper control eliminates the need for a microcomputer to increase the wiper transition rate. The accelerated auto-advance feature provides a wiper-changing rate at 4Hz for holding the control input low for more than 250ms and at 8Hz after 500ms and then at 11Hz after 1000ms.
