DS2890

OPERATION
The DS2890 is a single element digital potentiometer; a block diagram of the device is shown in Figure 1.
The device has a total of 256 linearly spaced tap points including the RL and RH terminals; a total of 255
resistive segments exist between the RL and RH terminals. These tap points are accessible to the WIPER
terminal whose position is controlled via the 1-Wire bus interface. Wiper position and device state are
maintained as long as the 1-Wire bus is active or the VDD supply is applied within operating limits.
Otherwise, a power-on reset will occur and the wiper position and operating state will return to power-on
default conditions.
FIGURE 1. DS2890 BLOCK DIAGRAM
As shown in the figure the device has five major elements: the 1-Wire Function Controller, the
Potentiometer Controller, the 64-bit ROM, the resistor array, and Parasite Power circuitry. Each of these
elements is discussed in detail throughout the remainder of the data sheet. DS2890 control including
device selection, positioning/reading the potentiometer wiper, and device operating state is performed
over the 1-Wire bus. The hierarchical structure of the 1-Wire protocol as applicable to the DS2890 is
shown in Figure 2. As shown, the control sequence starts with the 1-Wire bus master issuing one of eight
ROM function commands. After a ROM function command is successfully completed potentiometer
functions may be executed. The protocol for ROM and potentiometer functions are described in the
“COMMAND FLOW” section.
For the 3-pin TO-92 package configuration and operation see the
“TO-92 PACKAGE OPERATION” section.
