MAX5456EEE+

The MAX5456EEE+ is a stereo audio taper potentiometer with pushbutton interface in 16 pin QSOP package. This device is a dual logarithmic potentiometer used to control volume and balance in audio applications. Each potentiometer has 32-taps and the device uses digital inputs with momentary contact single-pole/single-throw (SPST) pushbutton switches. MAX5456 has advance wiper setting with once per button push. 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. It has 4-button interface with separate inputs for up and down volume controls, left and right balance controls.

• SmartWiper control provides accelerated wiper motion
• Debounced pushbutton interface with internal pull-up resistor
• Logarithmic taper with 2dB steps between taps
• Single +2.7V to +5.5V or dual ±2.7V supply operation
• Low standby supply current of 0.5µA
• Clickless switching
• Mute function to -90dB (typ)
• Power-on reset to -12dB wiper position
• End to end resistance is 10Kohm at ±30% tolerance and temperature coefficient is 50ppm/°C
• Ratiometric temperature coefficient of 5ppm/°C
