DESCRIPTION
The DS1844 Quad Digital Potentiometer is a four-channel, digitally controlled linear potentiometer. Each potentiometer is comprised of 63 equi-resistive sections and has three terminals accessible to the user. These include the high side terminals, HX, the wiper terminals, WX, and the low-side terminals, LX. The wiper position on the resistor ladder is selected via an 8-bit register value. Communication and control of the device are supported by two types of serial interface. These include a 5-wire I/O shift register interface and a 2-wire addressable interface.
