X9418WS24-2.7

Digital Potentiometers Overview

The X9418WS24-2.7 is a dual digitally controlled potentiometer (XDCP) featuring two independent 10 kΩ resistor arrays with 64 taps each. It operates on a 2-wire serial interface and includes nonvolatile memory for wiper position storage. The device supports supply voltages of VCC, V+, and V– ranging from 2.7V to 5.5V. Key electrical parameters include an end-to-end resistance tolerance of ±20%, a maximum wiper resistance of 150 Ω at ±3V supplies, and a standby current of less than 1 µA. It is housed in a 24-lead SOIC package.

Digital Potentiometers Feature Summary

• Variable resistive elements in signal processing

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized channels as the datasheet indicates this part is not recommended for new designs. Confirm package marking matches the specified 'X9418WS G' identifier. Ensure supply sequencing meets the requirement of applying VCC before analog supplies to guarantee correct register recall upon power-up.

Digital Potentiometers Selection Notes

Select this component when dual isolated potentiometers are required within a single package. The 10 kΩ value suits moderate impedance applications. Verify that the system can accommodate the 2-wire serial protocol and that the 64-step resolution meets the required adjustment granularity. Check that the operating temperature range aligns with commercial or industrial requirements.

Digital Potentiometers Part Context

This component belongs to the X9418 family of low noise, low power digitally controlled potentiometers manufactured by Renesas Electronics Corporation (formerly Intersil). The series integrates multiple potentiometers on a monolithic CMOS microcircuit, offering a solid-state alternative to mechanical potentiometers for parameter adjustments and control applications.

Digital Potentiometers Replacement Considerations

The datasheet explicitly states 'NO RECOMMENDED REPLACEMENT'. Engineers must contact the Technical Support Center for guidance on potential substitutes or design updates due to the component's status as not recommended for new designs.
