Digital Potentiometers datasheet and documents for DS1859E-050
Digital Potentiometers Overview
The DS1859E-050 is a dual, temperature-controlled, nonvolatile variable resistor IC featuring three analog monitor inputs and an integrated direct-to-digital temperature sensor. It contains two 50kΩ linear resistors with 256 positions, accessible via a 2-wire serial bus. The device operates on a 3.3V or 5V supply within a -40°C to +95°C range. Key electrical parameters include a supply voltage of 2.85V to 5.5V, a maximum supply current of 2mA, and a thermometer error of ±3.0°C across the operating temperature range.
Digital Potentiometers Feature Summary
- Dual 50kΩ, 256-position linear variable resistors with nonvolatile EEPROM storage
- Five monitored channels: Temperature, VCC, MON1, MON2, and MON3
- Configurable alarm and warning flags for all monitored signals
- SFF-8472 compatible with separate Main and Auxiliary device addresses
Digital Potentiometers Applications

Digital Potentiometers Procurement Notes
Verify component authenticity through authorized distributors. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices from Analog Devices/Maxim Integrated prior to procurement planning.
Digital Potentiometers Selection Notes
Select the DS1859E-050 specifically for its 50kΩ resistance value; the DS1859B-020 variant provides 20kΩ resistors. Ensure the design supports the 2-wire serial interface timing requirements for standard or fast mode operation.
Digital Potentiometers Part Context
This component belongs to the DS1859 family of dual temperature-controlled resistors. It is manufactured by Analog Devices Inc./Maxim Integrated and is designed for applications requiring precise bias control and diagnostic monitoring in optical networking equipment.
Digital Potentiometers Replacement Considerations
The DS1859B-050+ is a lead-free version of the same functional part number. Verify pinout and memory map compatibility before substitution.
