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 50 kΩ end-to-end resistance and 64 tap positions each. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, with an active supply current of 2 mA maximum. Control is managed via a 3-wire serial interface (RST, DIN, CLK), allowing individual wiper position setting through an 8-bit register per channel. The unit supports industrial operating temperatures from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Six independent digitally controlled potentiometers with 50 kΩ resistance and 64 tap positions
• 3-wire serial interface for reading and setting wiper positions
• Cascading capability allows multiple devices to be controlled by a single processor
• Volatile memory retains settings only while power is applied

Digital Potentiometers Applications

• Fixed gain attenuator circuits
• Multi-device control systems requiring cascaded digital potentiometry
• Industrial applications within the -40°C to +85°C temperature range

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the package type and resistance value. The 'E' suffix indicates the TSSOP package, while '050' denotes the 50 kΩ resistance. Ensure compatibility with the required 3-wire serial protocol and voltage levels before procurement.

Digital Potentiometers Selection Notes

Select this component when a multi-channel digital potentiometer solution is required. The DS1806E-050+ provides six channels, which is suitable for applications needing simultaneous adjustment of multiple parameters. Consider the volatile nature of the wiper positions; if non-volatile storage is required, alternative models such as the DS1804 or DS1859 series should be evaluated.

Digital Potentiometers Part Context

This part belongs to the DS1806 family of digital sextet potentiometers. Other variants in the series include the DS1806-010 (10 kΩ) and DS1806-100 (100 kΩ). Package options include 20-lead DIP, SOIC, and TSSOP. The E suffix specifically identifies the TSSOP package variant.

Digital Potentiometers Replacement Considerations

Direct replacements must match the six-channel configuration, 50 kΩ resistance, and 3-wire serial interface. Verify pinout compatibility, particularly the shared low-end terminals (L1-3 and L4-6), when substituting with other hex-digital potentiometer ICs.
