Digital Potentiometers datasheet and documents for DS2890-000

DS2890-000

Digital Potentiometers Overview

The DS2890-000 is a single-element, linear-taper digital potentiometer featuring 256 wiper positions and a 100 kΩ resistor element. It utilizes the 1-Wire bus interface for control and data transfer. The device supports potentiometer terminal working voltages up to 11V, which are independent of the 2.8V–6.0V supply voltage. It includes a unique factory-lasered 64-bit registration number for identification. The component operates within a temperature range of -40°C to +85°C and is housed in a TO-92 package.

Digital Potentiometers Feature Summary

Single element with 256-position linear taper and 100 kΩ resistance
Potentiometer terminals support working voltages up to 11V
Controlled via minimal 1-Wire bus interface
Includes unique 64-bit lasered ROM for absolute identity

Digital Potentiometers Applications

Industrial control systems requiring variable resistance
Multi-drop 1-Wire network environments
Applications needing terminal voltage independence from supply

Digital Potentiometers Procurement Notes

Verify the specific package type required, as the DS2890 family includes both TO-92 and TSOC variants. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure the 1-Wire bus master hardware configuration supports the necessary pull-up resistor values between 1.5 kΩ and 5 kΩ for reliable communication.

Digital Potentiometers Selection Notes

Select this model when a single-channel digital potentiometer with high terminal voltage tolerance is needed. The TO-92 package is suitable for through-hole mounting. Note that volatile memory requires an active bus or VDD supply to maintain position; otherwise, it resets to the power-on default. Verify if Overdrive mode speed requirements exceed standard 1-Wire limits.

Digital Potentiometers Part Context

The DS2890 belongs to the Maxim Integrated 1-Wire Digital Potentiometer family. It shares the 2Ch family code and protocol structure with other devices in the series but is distinguished by its single-element architecture and TO-92 packaging option. It functions as a slave device on the 1-Wire network, relying on a bus master for all operational commands.
