DS1806-100+

Digital Potentiometers Overview

The DS1806-100+ is a digital sextet potentiometer IC from Analog Devices/Maxim Integrated, featuring six independent 100 kΩ linear potentiometers. Each channel provides 64 discrete positions controlled via an 8-bit register value. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical active current of 2 mA. It utilizes a 3-wire serial interface (RST, DIN, CLK) for setting and reading wiper positions. The unit supports cascading for multi-device control and functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Six digitally controlled 100 kΩ linear potentiometers with 64 positions each
• 3-wire serial interface allows reading and setting individual wiper positions
• Cascading capability enables single-processor control of multiple devices
• Industrial operating temperature range: -40°C to +85°C

Digital Potentiometers Applications

• Fixed gain attenuator configurations
• Multi-device control systems requiring daisy-chaining
• Applications needing solid-state linear resistance adjustment

Digital Potentiometers Procurement Notes

Verify the specific package variant required, as the base model number corresponds to a 20-pin DIP. Suffixes such as 'S' indicate SOIC packages and 'E' indicates TSSOP packages. Confirm availability status through authorized distributors, as lead times may vary based on manufacturing cycles.

Digital Potentiometers Selection Notes

Select the DS1806-100+ when six independent 100 kΩ resistive paths are needed. Ensure the system voltage falls between 2.7 V and 5.5 V. For PCB space constraints, consider the SOIC or TSSOP variants instead of the standard DIP package. Verify that the 3-wire serial protocol matches the host processor's capabilities.

Digital Potentiometers Part Context

This component belongs to the DS1806 Digital Sextet Potentiometer family. Other variants in this series include the DS1806-010 (10 kΩ) and DS1806-050 (50 kΩ). All variants share identical pinouts, serial interfaces, and functional characteristics, differing only in end-to-end resistance values.

Digital Potentiometers Replacement Considerations

Direct substitutes include the DS1806-010+ and DS1806-050+ if resistance tolerance permits. Package-specific equivalents are available by appending suffixes like 'S' for SOIC or 'E' for TSSOP to the base part number.
