查看全系列相关产品产品概述
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
