MAX5457EEE+

The MAX5457EEE+ is a dual, stereo audio logarithmic taper potentiometer with pushbutton interface in 16 pin QSOP package. MAX5457 has 32-tap points and feature a simple pushbutton interface that controls volume and balance in audio applications. This device has a SmartWiper control which eliminates the need for a microcomputer to increase the wiper transition rate and hold the control input low for more than 1s which advances the wiper at a rate of 4Hz for 4s and 16Hz per second. The device has 3-button interface with a MODE input that toggles between volume and balance control modes.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 85°C
• Smartwiper control provides accelerated wiper motion

• Logarithmic taper with 2dB steps between taps
• low 0.5µA standby supply current
• 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
