Informace o produktu
Přehled produktu
The MAX5440EAG+ is a stereo volume control with rotary encoder interface in 24 pin SSOP package. The dual, 40Kohm logarithmic taper volume control features a debounced up/down interface for use with a simple rotary encoder without using a microcontroller. Each potentiometer has 32 log spaced tap points with a buffered wiper output and replaces mechanical potentiometers. An integrated bias generator provides required ((VDD + VSS)/2) bias voltage, eliminating need for costly external op-amp circuits in unipolar audio applications. A mode indicator LED output specifies volume or balance control. 5 integrated LED drivers indicate volume level or balance settings, depending on status of mode indicator. It includes debounced pushbutton inputs for mute and mode. The mode input toggles between volume and balance control. A click and pop suppression features minimizes audible noise generated by wiper transitions.
