ISL23318TFUZ-TK

Digital Potentiometers Overview

The ISL23318TFUZ-TK is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features a 10 kOhm total resistance with a linear taper and provides 128 discrete taps for precise adjustment. The device utilizes a serial I2C interface for control and includes volatile wiper memory to retain position during operation. It operates on a supply voltage ranging from 1.7 V to 5.5 V, with a typical operating current of 18 uA at 3.3 V. The component is housed in a 10-lead MSOP package and supports an extended industrial temperature range from -40°C to +125°C.

Digital Potentiometers Feature Summary

• Integrates a single digitally controlled potentiometer with 128 adjustable taps and linear resistance taper.
• Features a standard I2C serial interface allowing direct user control of wiper position via software commands.
• Includes volatile wiper storage that retains the last set position during active power cycles.

Digital Potentiometers Applications

• Precision signal conditioning and gain adjustment in sensor interfaces
• Calibration of analog circuits requiring programmable resistance values
• Volume or tone control in low-power audio equipment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TFUZ' against official Renesas documentation to confirm pinout compatibility and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Ensure the I2C address configuration matches system requirements before integration.

Digital Potentiometers Selection Notes

Select this component when a single-channel, low-pin-count digital potentiometer is required for space-constrained designs. The 10 kOhm value suits moderate impedance applications, while the I2C interface simplifies board routing compared to parallel alternatives. Verify that volatile memory behavior aligns with the application's power-loss tolerance.

Digital Potentiometers Part Context

This part belongs to the ISL23318 family of single-channel digital potentiometers. It shares core architectural similarities with other variants in the series but differs in packaging and specific ordering suffixes. The MSOP-10 package offers a compact footprint suitable for surface-mount assembly in portable or industrial electronics.

Digital Potentiometers Replacement Considerations

Consult official substitution guides for equivalent parts within the ISL23318 family. Verify pin-to-pin compatibility and electrical parameter alignment before replacing obsolete or limited-stock components.
