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, H_X, the wiper terminals, W_X, and the low-side terminals, L_X.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.
