X9409WV24I-2.7

Digital Potentiometers Overview

The X9409WV24I-2.7 is a quad digitally controlled potentiometer (XDCP) manufactured by Xicor, an Intersil division. It integrates four independent 10 kΩ resistive elements with linear taper on a single CMOS chip. Each potentiometer offers 64 tap positions for precise resistance adjustment. The device utilizes a 2-wire serial control interface for communication. It features non-volatile wiper memory to retain settings during power loss. Operating voltage ranges from 2.7 V to 5.5 V, with a typical supply current of 100 µA. It is housed in a 24-pin TSSOP package and operates within a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10 kΩ digital potentiometers

• Voltage reference trimming
• Digital volume control in audio systems
• Sensor bias adjustment

Digital Potentiometers Procurement Notes

Verify component authenticity as the manufacturer has undergone corporate restructuring. Confirm the specific suffix indicates the correct voltage range and package type. Check for moisture sensitivity labeling if storage conditions are critical. Ensure the source provides traceability to original manufacturing records given the age of the product line.

Digital Potentiometers Selection Notes

Select this part when a compact solution for multiple variable resistors is required without mechanical wear. The 2-wire interface reduces pin count compared to parallel interfaces. Verify that the 64-step resolution meets the application's precision requirements. Ensure the operating voltage aligns with the 2.7 V to 5.5 V specification.

Digital Potentiometers Part Context

This component belongs to the X9409 family of quad digitally controlled potentiometers. It shares architectural similarities with other members like the X9408 but differs in resistance value. The part represents the legacy Xicor technology acquired by Intersil and later Renesas. It serves as a solid-state alternative to traditional mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct replacements include the X9409WB241I-2.7 which uses a BGA/CSP package instead of TSSOP. Other family members may offer different resistance values or interface types. Verify pin compatibility and electrical parameters before substituting.
