ISL23318TFUZ-T7A

Digital Potentiometers Overview

The ISL23318TFUZ-T7A is a digital potentiometer manufactured by Renesas Electronics Corporation. It features a single circuit with a resistance value of 50k ohms and 128 taps, controlled via an I2C interface. The device operates within a supply voltage range of 1.2V to 5.5V or 1.7V to 5.5V, depending on the specific configuration. It utilizes volatile memory for wiper position storage and offers selectable address capabilities. The component is housed in a 10-UTQFN package measuring 2.1x1.6 mm and supports a linear taper. It is designed for surface mount installation and functions across a temperature range of -40°C to 125°C.

Digital Potentiometers Feature Summary

• I2C serial interface control for digital adjustment
• Selectable slave address configuration
• Linear taper resistance profile
• Compact 10-terminal ultra-thin quad flat no-lead packaging

Digital Potentiometers Applications

• Programmable gain amplifier circuits
• Voltage reference trimming
• Audio volume control systems
• Sensor bias adjustment

Digital Potentiometers Procurement Notes

Verify the exact suffix 'TFUZ' against official Renesas documentation, as standard listings often cite 'UFRUZ'. Confirm current manufacturing status, as related variants have been marked obsolete. Ensure the 10-UTQFN (2.1x1.6) package matches design constraints. Validate RoHS compliance and moisture sensitivity level requirements before integration into production schedules.

Digital Potentiometers Selection Notes

Select this component when a low-profile, digitally adjustable resistor is required for space-constrained designs. The I2C interface simplifies board routing compared to parallel interfaces. Consider the volatile memory characteristic, which requires state restoration upon power-up if wiper position retention is critical. The wide operating voltage range supports both low-power and standard logic systems.

Digital Potentiometers Part Context

This part belongs to the XDCP series of digital potentiometers from Renesas. It serves as a solid-state alternative to mechanical potentiometers, offering higher reliability and longer lifespan in automated environments. The series is commonly used in industrial and consumer electronics where precise, software-controlled resistance adjustment is necessary without physical user interaction.

Digital Potentiometers Replacement Considerations

Public records indicate the ISL23318UFRUZ-TK as a substitute for the discontinued ISL23318UFRUZ-T7A variant. Verify pinout compatibility and package dimensions between the TFUZ and UFRUZ suffixes before substitution.
