DS1802S+

The DS1802S+ is a dual audio logarithmic taper potentiometer with pushbutton control in 20 pin WSOIC package. It can be operated under automatic software control via a serial 3-wire interface where wiper settings are written with 8bit words or under pushbutton control with simple contact closure. DS1802 supports daisy-chaining with other devices under single processor control. It features four contact closure points for pushbutton control. When combined with mode control, this device allows eight different pushbutton control functions. Secondly, the DS1802's potentiometers can be controlled separately or in stereo mode control where wipers from both pots are positioned together from one control input. It ideally provides high-performance audio volume and tone control in most applications including CD players, guitar amplifiers and sound boards.
