MAXIM INTEGRATED PRODUCTS  MAX5457EEE+  易失性数字电位器, SPST, 10 kohm, 双, 按钮, 对数（音频）, ± 30%, 2.7 V

The 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.
