DS1806S-010

Digital Potentiometers Overview

The DS1806S-010 is a six-channel digital potentiometer IC in a 20-pin SOIC package. It features six linear potentiometers, each with 64 positions (10 kΩ resistance). Control is via a 3-wire serial interface (RST, DIN, CLK) using an 8-bit register per wiper. The device operates on 2.7V to 5.5V supply voltage with active current of 2 mA. It supports cascading for multi-device control and includes absolute linearity of ±0.5 LSB.

Digital Potentiometers Feature Summary

• Six digitally controlled 64-position linear potentiometers
• 3-wire serial interface for reading and setting wiper positions
• Cascadable architecture for single processor multi-device control
• 10 kΩ standard resistance value with ±20% tolerance

Digital Potentiometers Applications

• Fixed gain attenuator configurations
• Multi-device control systems requiring daisy-chaining
• Industrial temperature range applications (-40°C to +85°C)

Digital Potentiometers Procurement Notes

Verify the specific suffix 'S' indicates the 20-pin SOIC package variant. Confirm the '-010' designation corresponds to the 10 kΩ resistance version. Check for RoHS compliance status as indicated in manufacturer documentation. Ensure availability matches the industrial temperature grade specifications.

Digital Potentiometers Selection Notes

Select this model when six independent digital potentiometers are required in a surface-mount package. The 10 kΩ value suits moderate impedance circuits. Verify that the 3-wire serial protocol aligns with the host microcontroller's available interfaces. Consider the shared low-end terminals (L1-3 and L4-6) when designing circuit topology.

Digital Potentiometers Part Context

This component belongs to the DS1806 Digital Sextet Potentiometer family. Other variants include the DIP (DS1806) and TSSOP (DS1806E) packages. Resistance options are 10 kΩ, 50 kΩ, and 100 kΩ. The series is characterized by its ability to cascade multiple units for expanded control capabilities.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same package type include DS1806S-050 and DS1806S-100 for different resistance values. Cross-package equivalents exist as DS1806-010 (DIP) and DS1806E-010 (TSSOP), though physical mounting differences must be accounted for.
