ISL23318WFUZ

Digital Potentiometers Overview

The ISL23318WFUZ is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features a resistance value of 10 kOhms with a linear taper and offers 128 tap positions for precise adjustment. The device utilizes a volatile memory type to store wiper settings and communicates via a Serial I2C interface. It operates within a supply voltage range of 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 surface mount installation. It functions reliably across an extended temperature range from -40°C to +125°C.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 10 kOhm resistance and linear taper
• 128 tap positions controlled via I2C serial interface
• Volatile wiper memory retains settings during power cycles
• Operates on supply voltages between 1.7 V and 5.5 V

Digital Potentiometers Applications

• Industrial control systems requiring adjustable gain or reference voltages
• Consumer electronics needing programmable volume or brightness control
• Test and measurement equipment utilizing calibrated signal paths

Digital Potentiometers Procurement Notes

Verify availability status as distribution channels may indicate limited stock or end-of-life conditions. Confirm RoHS compliance details through official datasheets before procurement. Check for specific ordering suffixes that may affect packaging or tape-and-reel quantities. Ensure compatibility with existing PCB footprints for the 10-MSOP package.

Digital Potentiometers Selection Notes

Select this component when a single digital potentiometer with I2C control is required. The 10 kOhm value suits moderate impedance applications. Consider the volatile memory characteristic if non-vatole retention is needed, as it requires external storage solutions. The 128 taps provide sufficient resolution for many general-purpose adjustments without excessive complexity.

Digital Potentiometers Part Context

This part belongs to the ISL23318 family of digital potentiometers. It shares architectural similarities with other members like the ISL23318UFRUZ but differs in package type (MSOP vs UFQFN) and potentially resistance values. The WFUZ suffix typically denotes the specific package and temperature grade configuration within the product line.

Digital Potentiometers Replacement Considerations

Direct substitutes include other ISL23318 variants with compatible interfaces and pinouts. Verify electrical parameters such as resistance tolerance and operating voltage ranges when cross-referencing with alternative digital potentiometer models from Renesas or other manufacturers.
