ISL23325TFVZ

Digital Potentiometers Overview

The ISL23325TFVZ is a dual-channel digital potentiometer IC from the ISL23325 series, manufactured by Renesas Electronics. It features two independent potentiometers, each with 256 taps and a resistance value of 100 kOhms. The device utilizes a volatile arc brush memory to store wiper positions and communicates via an I2C serial 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 14-lead TSSOP package and supports a linear taper configuration.

Digital Potentiometers Feature Summary

• Dual channel architecture with 256 taps per potentiometer
• I2C serial interface for digital control
• 100 kOhms nominal resistance with 20% tolerance
• Volatile memory storage for wiper settings

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control circuits

Digital Potentiometers Procurement Notes

Verify the specific suffix TFVZ against the manufacturer's datasheet to confirm the TSSOP-14 package and tube packaging details. Confirm RoHS compliance status through official documentation before procurement. Check for obsolescence notices as this component may be subject to lifecycle changes.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital potentiometer with high resistance (100 kOhms) and I2C connectivity is required. Ensure the application can tolerate volatile memory behavior, as wiper positions are lost upon power cycle. Verify that the 1.7 V to 5.5 V supply range aligns with the system design constraints.

Digital Potentiometers Part Context

This part belongs to the ISL23325 family of digital potentiometers. It shares architectural similarities with other members like the ISL23325UFRUZ-TK but differs in package type (TSSOP vs UQFN) and resistance value (100 kOhms vs 50 kOhms). The TFVZ suffix specifically denotes the TSSOP-14 surface mount package variant.

Digital Potentiometers Replacement Considerations

Direct replacements must match the dual-channel, 100 kOhm, I2C specification. Consider the ISL23325UFRUZ-TK if a smaller UQFN package is acceptable and 50 kOhm resistance is permissible. Verify pin compatibility and electrical parameters before substitution.
