Digital Potentiometers datasheet and documents for DS3904U-010+

DS3904U-010+

Digital Potentiometers Overview

The DS3904U-010+ is a triple nonvolatile digital variable resistor and switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates three linear digital resistors with end-to-end resistance values of 20kΩ, 10kΩ, and 20kΩ for Resistor 0, 1, and 2 respectively. Each resistor offers 128 user-selectable positions plus a high-impedance setting for switch operation. The device operates on a 2.7V to 5.5V supply voltage range and communicates via a 2-wire serial interface. Resistor settings are stored in nonvolatile memory, ensuring retention during power loss.

Digital Potentiometers Feature Summary

Triple digital resistors: 20kΩ (R0), 10kΩ (R1), and 20kΩ (R2) with 128 tap positions each
Nonvolatile memory retains resistor settings without external power
High-impedance mode allows resistors to function as digital switches
2-wire serial interface supports standard (100kHz) and fast (400kHz) modes

Digital Potentiometers Applications

Power-supply calibration
Fibre optic transceiver modules
Portable electronics such as cell phones and PDAs
Test equipment requiring automated trimming

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix '010' confirms the 20/10/20kΩ resistance configuration. Confirm the package type is 8-pin µSOP. Check current availability status as this component may be subject to lifecycle changes or discontinuation notices from the manufacturer.

Digital Potentiometers Selection Notes

Select the DS3904U-010+ when a single IC replacement for mechanical trimmers is required with mixed resistance values. Ensure the design utilizes a 2-wire serial bus compatible with standard I2C-like protocols. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements.

Digital Potentiometers Part Context

This part belongs to the DS3904/DS3905 family of triple nonvolatile digital potentiometers. The DS3904 variant specifically features one address pin (A0), allowing two devices to share the same serial bus. This contrasts with the DS3905, which has three address pins for up to eight devices on a common bus.
