X9418WS24-2.7T1

Digital Potentiometers Overview

The X9418WS24-2.7T1 is a dual digitally controlled potentiometer (XDCP) from the X9418 series, manufactured by Renesas Electronics Corporation. It integrates two independent 10 kΩ resistor arrays, each providing 64 taps for precise resistance adjustment. The device utilizes a 2-wire serial interface (SCL/SDA) for communication and includes nonvolatile memory to retain wiper positions. It operates within a supply voltage range of 2.7V to 5.5V and supports analog supplies from ±2.7V to ±5.5V. Packaged in a 24-lead SOIC with a tape and reel suffix, it features low power consumption and hardware write protection.

Digital Potentiometers Feature Summary

• Dual potentiometers with 10 kΩ end-to-end resistance and 64 tap resolution per channel
• 2-wire serial interface supporting direct read/write/transfer of wiper positions and data registers
• Nonvolatile memory storing up to four distinct wiper positions per potentiometer with 100-year retention
• Hardware Write Protect (WP) pin to prevent unintended nonvolatile writes

Digital Potentiometers Applications

• Control and parameter adjustments in electronic circuits
• Signal processing applications requiring variable gain or attenuation
• Battery-operated systems due to low standby current (<1µA)

Digital Potentiometers Procurement Notes

Verify that the ordering suffix T1 confirms the tape and reel packaging format. Confirm the specific temperature grade associated with the WS24 designation against the manufacturer's current documentation, as industrial ratings may vary. Ensure the component meets RoHS compliance requirements if applicable to the assembly process.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital potentiometer with nonvolatile storage is required. The 10 kΩ resistance value suits moderate impedance applications. Verify that the host system supports the 2-wire serial protocol and can provide the necessary address bits via A0-A3 pins. Ensure the analog supply rails fall within the ±2.7V to ±5.5V range for proper operation.

Digital Potentiometers Part Context

This part belongs to the X9418 family of low noise, low power XDCPs. The 'WS' indicates a 24-lead SOIC package, while 'Z' denotes Pb-free construction. The '-2.7' suffix specifies the extended voltage range capability down to 2.7V. The 'T1' suffix specifically identifies the tape and reel shipping configuration.
