DS2890P-000+

Digital Potentiometers Overview

The DS2890P-000+ is a single-element, linear-taper digital potentiometer featuring 256 wiper positions and a 100 kΩ resistor element. It utilizes the 1-Wire interface for control and data transfer. The device supports terminal working voltages up to 11V, 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 6-pin TSOC package.

Digital Potentiometers Feature Summary

• Single element 256-position linear taper potentiometer with 100 kΩ resistance
• 1-Wire bus interface for wiper position control and reading
• Potentiometer terminal voltage support up to 11V, independent of supply
• Unique 64-bit lasered ROM for absolute part identity

Digital Potentiometers Applications

• Industrial control systems requiring remote resistance adjustment
• Multi-drop 1-Wire network environments
• Applications needing variable resistor or potentiometer configurations

Digital Potentiometers Procurement Notes

Verify component authenticity through official Analog Devices channels due to discontinued status. Confirm package type matches the 6-pin TSOC specification. Check for RoHS3 compliance documentation. Ensure compatibility with existing 1-Wire bus infrastructure. Review datasheet for pull-up resistor requirements.

Digital Potentiometers Selection Notes

Select this model for applications requiring a single digital potentiometer with 1-Wire connectivity. Ensure the system supports the 2.8V to 6.0V supply range. Verify that the 100 kΩ resistance value meets circuit requirements. Consider the 6-pin TSOC package constraints for PCB layout. Confirm operating temperature range suitability for the environment.

Digital Potentiometers Part Context

The DS2890 series includes variants such as DS2890-000 (TO-92) and DS2890P-000 (TSOC). The P suffix denotes the surface-mount TSOC package. Other family members may offer different resistance values or pinouts. The DS2890 is part of the broader 1-Wire product line from Maxim Integrated/Analog Devices.
