ISL22416UFRT10Z

Digital Potentiometers Overview

The ISL22416UFRT10Z is a single Digitally Controlled Potentiometer (XDCP) integrating non-volatile memory and an SPI interface. It features 128 resistor taps with a total resistance of 10kΩ, operating on a single supply from 2.7V to 5.5V. The device includes a volatile Wiper Register (WR) and a non-volatile Initial Value Register (IVR), allowing the wiper position to be recalled at power-up. It supports shutdown mode with a maximum current of 5µA and offers high reliability with 1,000,000 endurance cycles and 50-year data retention.

Digital Potentiometers Feature Summary

• Single DCP with 128 taps and 10kΩ total resistance
• SPI serial interface with non-volatile wiper storage
• Shutdown mode with 5µA max current consumption
• Extended industrial temperature range (-40°C to +125°C)

Digital Potentiometers Applications

• Control systems requiring parameter adjustments
• Signal processing applications
• Portable battery-powered devices

Digital Potentiometers Procurement Notes

Verify that the component matches the 10 Ld 3x3 TDFN package specification. Confirm the 10kΩ resistance option is required, as a 50kΩ variant exists. Ensure the ordering suffix aligns with the specific tape and reel requirements if applicable, referencing TB347 for details.

Digital Potentiometers Selection Notes

Select this model for designs requiring a single potentiometer channel with persistent settings across power cycles. The 10kΩ resistance option is suitable for moderate impedance circuits. Verify that the host system supports the SPI protocol mode 0 and provides the necessary voltage levels for the 2.7V to 5.5V operating range.

Digital Potentiometers Part Context

This part is manufactured by Renesas Electronics Corporation (formerly Intersil). It belongs to the XDCP family of digitally controlled potentiometers. The datasheet indicates it is not recommended for new designs, suggesting potential obsolescence or replacement by newer models in the product line.

Digital Potentiometers Replacement Considerations

The datasheet identifies the ISL22316 as a possible substitute product. Verify pin compatibility and interface differences, as the ISL22316 utilizes an I2C bus instead of SPI.
