DS1804U-100+T&R

Digital Potentiometers Overview

The DS1804U-100+T&R is a single-channel nonvolatile digital potentiometer with a resistance of 100kΩ and 100 tap positions. It operates on supply voltages from 2.7V to 5.5V, consuming 400µA during operation. The device features an increment/decrement interface controlled by CS, INC, and U/D pins. Wiper position data is stored in EEPROM for retention across power cycles. It is housed in an 8-pin µSOP package and supports an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile wiper storage via EEPROM
• Increment/Decrement control interface
• Single channel with 100 tap positions
• Industrial operating temperature (-40°C to +85°C)

Digital Potentiometers Applications

• Low-cost trimming applications using CPU or manual control
• Portable equipment requiring low power consumption
• Calibration circuits needing persistent settings

Digital Potentiometers Procurement Notes

Verify the component matches the specific 100kΩ resistance grade and 8-pin µSOP package configuration. Confirm that the ordering suffix corresponds to the required tape and reel quantity if applicable. Ensure the RoHS compliance status aligns with project requirements.

Digital Potentiometers Selection Notes

Select this model when a 100kΩ total resistance is required. Consider alternative grades (DS1804U-010 for 10kΩ or DS1804U-050 for 50kΩ) if different resistance values are needed. Verify that the 3-terminal control interface fits the system architecture.

Digital Potentiometers Part Context

This part belongs to the DS1804 family of nonvolatile trimmer potentiometers. It shares the same core functionality as other variants but differs in resistance value and physical packaging. The 'U' designation indicates the µSOP package type.

Digital Potentiometers Replacement Considerations

Direct replacements include DS1804U-010+ and DS1804U-050+ for different resistance values within the same package. Other packages like DIP or SOIC are available as DS1804-100+ and DS1804Z-100+ respectively.
