DS1806E-010

Digital Potentiometers Overview

The DS1806E-010 is a six-channel, digitally controlled solid-state linear potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features six independent 64-position potentiometers with a standard resistance value of 10 kΩ. Each wiper position is selected via an 8-bit register value accessed through a 3-wire serial port interface (RST, DIN, CLK). The device supports cascading for multi-device control and operates within an industrial temperature range of -40°C to +85°C. It utilizes a 20-pin TSSOP package.

Digital Potentiometers Feature Summary

• Six digitally controlled 64-position linear potentiometers
• 3-wire serial interface for reading and setting wiper positions
• Cascadable architecture allowing single processor control of multiple devices
• Standard 10 kΩ resistance value with ±0.50 LSB absolute linearity

Digital Potentiometers Applications

• Fixed gain attenuator configurations
• Multi-device control systems requiring daisy-chaining
• Digital volume or tone control circuits
• Programmable bias voltage generation

Digital Potentiometers Procurement Notes

Verify the specific package type and resistance tolerance against project requirements. Confirm that the 3-wire serial protocol timing aligns with the host microcontroller capabilities. Ensure operating conditions remain within the specified -40°C to +85°C industrial temperature range and supply voltage limits of 2.7V to 5.5V.

Digital Potentiometers Selection Notes

Select the DS1806E-010 when six independent digital potentiometers are required in a compact TSSOP footprint. The 10 kΩ end-to-end resistance is suitable for general-purpose signal attenuation. Consider the DS1806S-010 or DS1806-010 if SOIC or DIP packages are preferred instead of TSSOP.

Digital Potentiometers Part Context

The DS1806 series includes variants with 10 kΩ, 50 kΩ, and 100 kΩ resistances. The 'E' suffix denotes the 20-pin TSSOP package, while 'S' indicates SOIC and no suffix indicates DIP. All variants share identical electrical characteristics and functionality, differing only in physical packaging and total resistance.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other DS1806 variants such as DS1806S-010 (SOIC) or DS1806-010 (DIP). Cross-brand replacements require verification of serial interface compatibility and wiper resistance specifications.
