X9418WV24I-2.7T1

Digital Potentiometers Overview

The X9418WV24I-2.7T1 is a dual digitally controlled potentiometer (XDCP) from the XDCP series, manufactured by Renesas Electronics Corporation. It integrates two independent potentiometers within a single package, each featuring 64 taps and a resistance of 10 kΩ. The device utilizes a 2-wire serial interface for communication and includes nonvolatile memory to retain wiper positions. It operates with a system supply voltage (VCC) of 5V ±10% and supports analog supplies (V+, V-) ranging from 2.7V to 5.5V. The component is housed in a 24-lead TSSOP package and is designed for low power consumption, making it suitable for battery-operated applications.

Digital Potentiometers Feature Summary

• Dual potentiometer configuration with 64 taps per pot and 10 kΩ resistance.
• 2-wire serial interface supporting direct read/write/transfer of wiper positions.
• Nonvolatile memory storing up to four positions per potentiometer with 100-year retention.
• Low power CMOS technology with standby current less than 1µA.

Digital Potentiometers Applications

• Control and parameter adjustments in electronic circuits.
• Signal processing applications requiring variable resistance.
• Battery-operated devices due to low power consumption.
• Voltage regulator offset adjustment circuits.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'T1' indicates tape and reel packaging as per the datasheet. Confirm that the 'I' suffix corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 24-lead TSSOP package dimensions. Check for RoHS compliance status if required by assembly specifications.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital potentiometer with nonvolatile storage is required. The 10 kΩ resistance value must match the circuit design requirements. Ensure the host microcontroller supports the 2-wire serial protocol. Verify that the supply voltages align with the specified ranges for VCC and analog supplies.

Digital Potentiometers Part Context

This part belongs to the X9418 family of low noise, low power digitally controlled potentiometers. It is an evolution of earlier Intersil designs now produced by Renesas. The device is not recommended for new designs according to the datasheet, indicating potential obsolescence or replacement recommendations by the manufacturer.

Digital Potentiometers Replacement Considerations

The datasheet explicitly states 'NO RECOMMENDED REPLACEMENT'. Contact the Technical Support Center for potential alternatives. Cross-reference with other X9418 variants for pin compatibility, but verify electrical parameters carefully.
