ISL23315UFRUZ-TK

Digital Potentiometers Overview

The ISL23315UFRUZ-TK is a single, low-voltage Digitally Controlled Potentiometer (XDCP) manufactured by Renesas Electronics. It features a 50 kOhm resistance value with 256 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. Designed for surface-mount applications, it is housed in a compact 16-UTQFN package and supports an industrial operating temperature range from -40°C to +125°C.

Digital Potentiometers Feature Summary

• Single potentiometer configuration with 50 kOhm nominal resistance and 256 discrete tap positions.
• I2C compatible digital interface for wiper control and status reading.
• Volatile memory retains settings only while power is applied.
• Operates on a wide supply voltage range from 1.7 V to 5.5 V.

Digital Potentiometers Applications

• Low voltage programmable gain amplifier circuits
• Digital volume control in audio systems
• Calibration of sensor reference voltages

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against the official datasheet to confirm tape and reel packaging specifications. Confirm that the volatile memory type aligns with system requirements, as data is lost upon power removal. Ensure the I2C address configuration matches the target bus topology.

Digital Potentiometers Selection Notes

Select this component when a single-channel, low-voltage digital potentiometer with I2C control is required. The 50 kOhm resistance and 256-tap resolution suit moderate precision adjustment needs. Consider the volatile nature of the memory; if non-volatile retention is necessary, verify if alternative models in the series offer EEPROM storage.

Digital Potentiometers Part Context

This part belongs to the ISL23315 family of XDCPs. It shares architectural similarities with other members like the ISL23325, differing primarily in interface or pinout configurations. The UFRUZ suffix indicates the specific 16-UTQFN package variant used for surface mounting.

Digital Potentiometers Replacement Considerations

Direct substitutes include other single-channel I2C digital potentiometers with similar resistance and voltage ratings. Verify pin compatibility and memory volatility before swapping with variants like the ISL23315TFRUZ-T7A.
