DS1806E-050

Digital Potentiometers Overview

The DS1806E-050 is a six-channel digital potentiometer IC from Analog Devices/Maxim Integrated, housed in a 20-pin TSSOP package. It features six linear potentiometers with 64 positions each and a nominal resistance of 50 kΩ. The device operates on a supply voltage between 2.7 V and 5.5 V, consuming up to 2 mA active current. Control is managed via a 3-wire serial interface (RST, DIN, CLK), allowing individual wiper position setting through an 8-bit register. The unit supports industrial temperatures from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Six independent 64-position linear potentiometers with 50 kΩ nominal resistance
• 3-wire serial interface for reading and writing wiper positions
• Cascading capability via COUT pin for multi-device control
• "Don't change" feature using bits 6 and 7 of the wiper register

Digital Potentiometers Applications

• Fixed gain attenuator circuits
• Multi-device control systems requiring single processor management
• Industrial temperature environment applications

Digital Potentiometers Procurement Notes

Verify component authenticity and datasheet alignment before procurement. Confirm the specific suffix 'E' corresponds to the 20-pin TSSOP package variant. Check for end-of-life status or obsolescence notices from the manufacturer prior to finalizing orders.

Digital Potentiometers Selection Notes

Select this model when six digitally controlled resistors are required in a compact surface-mount package. Ensure the system utilizes a 3-wire serial protocol compatible with RST, DIN, and CLK signals. Verify that the 50 kΩ resistance value fits the circuit design requirements compared to the 10 kΩ or 100 kΩ alternatives.

Digital Potentiometers Part Context

This component belongs to the DS1806 series of digital sextet potentiometers. The 'E' suffix specifically denotes the 20-lead Thin-Shrink Small Outline Package (TSSOP) with a 173-mil width. Other variants include the DIP and SOIC packages, while the '-050' indicates the 50 kΩ resistance version within the family.

Digital Potentiometers Replacement Considerations

Direct replacements include other DS1806 series members such as DS1806S-050 (SOIC) or DS1806-050 (DIP). Cross-family substitutes require matching the 6-channel architecture, 3-wire serial interface, and 50 kΩ resistance value.
