X9418WS24IZ-2.7

Digital Potentiometers Overview

The X9418WS24IZ-2.7 is a dual digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates two independent potentiometers within a single 24-lead SOIC package. Each potentiometer features a 64-tap resolution and an end-to-end resistance of 10 kΩ. The device utilizes a 2-wire serial interface for control and includes nonvolatile memory to retain wiper positions. Operating specifications include a supply voltage range of 2.7V to 5.5V for VCC and V+, with V- ranging from -2.7V to -5.5V. The industrial temperature rating spans from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual potentiometer architecture with 64 taps per channel
• Nonvolatile data registers store up to four wiper positions each
• 2-wire serial bus interface with hardware write protect capability
• Low power CMOS design with standby current under 1µA

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing applications requiring variable gain or attenuation
• Battery-operated systems due to low standby current consumption

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'IZ' indicates Pb-free plus anneal construction compliant with RoHS standards. Ensure the ordering code matches the required 10kΩ resistance value and 24-lead SOIC package format for PCB integration.

Digital Potentiometers Selection Notes

Select this model when a dual-channel digital potentiometer with nonvolatile storage is required. The 10kΩ resistance value suits moderate impedance applications. Verify that the system supports the 2-wire serial protocol and that the available address pins (A0-A3) allow for unique device identification on the bus. Ensure supply voltages align with the specified ±2.7V to 5.5V ranges.

Digital Potentiometers Part Context

This component belongs to the X9418 family of low noise, low power digitally controlled potentiometers. The 'WS' designation identifies the 24-lead SOIC package variant, while 'I' denotes the industrial temperature range. The 'Z' suffix confirms lead-free manufacturing. This part serves as a solid-state replacement for mechanical potentiometers in precision adjustment roles.

Digital Potentiometers Replacement Considerations

Public documentation explicitly states 'NOT RECOMMENDED FOR NEW DESIGNS' and provides 'NO RECOMMENDED REPLACEMENT'. Engineers should consult the manufacturer's technical support center for potential modern equivalents or alternative solutions.
