DS1804U-100+

Digital Potentiometers Overview

The DS1804U-100+ is a nonvolatile digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features a single potentiometer with 100 tap positions and a resistance of 100kΩ. The device operates on supply voltages ranging from 2.7V to 5.5V, with a typical standby current of 20µA at 5V. It utilizes an increment/decrement interface controlled via CS, INC, and U/D pins. The component supports wiper position storage in EEPROM and functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile wiper storage capability using onboard EEPROM
• Increment/Decrement control interface (CS, INC, U/D)
• Single 100-position linear taper potentiometer
• Industrial operating temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Low-cost trimming applications with CPU or manual control
• Portable equipment requiring minimal external circuitry
• Industrial parameter adjustment

Digital Potentiometers Procurement Notes

Verify the package type matches the 'U' suffix for 8-pin µSOP. Confirm the resistance value corresponds to the '-100' designation for 100kΩ. Ensure the ordering suffix '+' indicates lead-free/RoHS compliance as per manufacturer specifications.

Digital Potentiometers Selection Notes

Select this model for applications requiring a 100kΩ nonvolatile digital potentiometer in a compact surface-mount package. Consider the 100 tap resolution and ±20% end-to-end resistor tolerance. Verify that the 3-terminal control interface aligns with the system's GPIO availability.

Digital Potentiometers Part Context

This component belongs to the DS1804 series of nonvolatile trimmer potentiometers. The 'U' suffix denotes the 8-pin µSOP package variant, while '100' specifies the 100kΩ resistance grade. The '+' suffix indicates RoHS-compliant packaging.

Digital Potentiometers Replacement Considerations

Compatible variants include DS1804Z-100+ (SOIC package) and DS1804-100+ (DIP package). These share identical electrical characteristics but differ in physical footprint.
