ISL23315TFRUZ-TK

Digital Potentiometers Overview

The ISL23315TFRUZ-TK is a single-channel, low-voltage Digitally Controlled Potentiometer (XDCP) manufactured by Renesas Electronics. It features a 10 kOhm resistance value with 256 taps and a linear taper. The device utilizes a volatile memory architecture and communicates via an I2C serial interface. Operating within a supply voltage range of 1.7 V to 5.5 V, it draws a typical operating current of 18 uA. The component supports an extended industrial temperature range from -40°C to +125°C and is housed in a compact 16-UTQFN surface-mount package.

Digital Potentiometers Feature Summary

• Single potentiometer circuit with 256 adjustable taps for precise resistance control
• I2C serial interface compatible with standard communication protocols
• Low power consumption with 18 uA operating current at 3.3 V
• Wide operating voltage range supporting 1.7 V to 5.5 V supplies

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Sensor calibration and offset adjustment
• Variable gain amplifier settings

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TFRUZ' against official Renesas documentation to confirm the exact tape-and-reel packaging configuration and pinout compatibility. Confirm RoHS compliance status through the manufacturer's latest datasheet revision notes before finalizing procurement specifications.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with I2C control is required. Ensure the 10 kOhm resistance value aligns with the target circuit impedance. Verify that the volatile memory characteristic is acceptable, as resistance settings will reset upon power loss. Check that the 16-UTQFN footprint fits the available PCB space.

Digital Potentiometers Part Context

This part belongs to the ISL23315 series of XDCP devices. It shares architectural similarities with other members like the ISL23315UFRUZ-TK but differs in resistance value and package type. The series is designed for applications requiring non-volatile or volatile digital adjustment of analog parameters in low-power systems.

Digital Potentiometers Replacement Considerations

Direct replacements include other ISL23315 variants with matching I2C interfaces and similar resistance values. Cross-reference with ISL23315WFUZ for pin-compatible alternatives if package differences are manageable. Verify electrical parameters such as wiper resistance and temperature coefficients for functional equivalence.
