ISL23318WFRUZ-TK

Digital Potentiometers Overview

The ISL23318WFRUZ-TK is a single-channel digital potentiometer IC from the Renesas XDCP series. It features a 10 kOhm resistance value with 128 taps and utilizes a volatile memory architecture for wiper position storage. The device communicates via an I2C serial interface and operates within a supply voltage range of 1.7 V to 5.5 V, drawing a typical operating current of 18 uA. It is housed in a 10-lead MSOP package and supports a linear taper configuration. The component is rated for operation between -40°C and +125°C.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 128 tap resolution
• I2C serial interface for control and data transfer
• Volatile wiper memory retains settings only during power
• Linear taper resistance profile

Digital Potentiometers Applications

• Variable gain amplifier control
• Voltage reference adjustment
• Programmable filter frequency setting

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status directly with the supplier documentation. Check for obsolescence notices or lifecycle changes on the Renesas website before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a single-channel, low-pin-count digital potentiometer is required. Ensure the system design accounts for volatile memory behavior, as wiper positions reset upon power loss. Verify that the I2C bus speed and address configuration are compatible with the host controller requirements.

Digital Potentiometers Part Context

This part belongs to the ISL23318 family of digitally controlled potentiometers. It shares core architectural similarities with other members like the ISL23318WFUZ but differs in packaging and shipping format. The family is designed for applications requiring precise, software-adjustable resistance values in compact form factors.

Digital Potentiometers Replacement Considerations

ISL23318WFUZ-TK is a documented alternative offering identical electrical characteristics in a different package style.
