DS1802+

The DS1802+ is a dual audio Taper Potentiometer with pushbutton control. The DS1802 is a dual audio taper-potentiometer having logarithmic resistive characteristics over the device range. Each potentiometer provides 65 wiper positions with a 1dB increment per step and device mute. The DS1802 has two methods of device control, which include contact closure (pushbutton) inputs and a 3-wire serial interface for wiper positioning. The pushbutton control inputs provide a simple interface for device control without the need for a CPU. While the 3-wire serial interface, using a CPU, provides the user the ability of reading or writing exact wiper positions of the two potentiometers. The DS1802 can also be configured to operate in either independent or stereo modes when using pushbutton control. Independent mode of operation allows for independent wiper control and stereo mode of operation provides single input control over both potentiometer wiper positions.
