ISL23325WFRUZ-TK

Digital Potentiometers Overview

The ISL23325WFRUZ-TK is a dual-channel, low-voltage digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features two independent potentiometers, each with 256 tap positions and a resistance value of 50 kOhms. The device utilizes an I²C digital interface for control and employs volatile memory to retain wiper settings during operation. It operates within a supply voltage range of 1.2V to 5.5V and supports a linear taper configuration. The component is housed in a 16-UTQFN package and is rated for industrial temperatures from -40°C to +125°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 taps per potentiometer
• I²C serial interface with selectable address capability
• Wide supply voltage range: 1.2V to 5.5V
• Linear taper with ±20% resistance tolerance

Digital Potentiometers Applications

• Volume control in audio equipment
• Programmable gain adjustment in signal conditioning circuits
• Voltage reference trimming in measurement systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'TK' against the manufacturer's current datasheet to confirm tape and reel packaging specifications. Confirm that the volatile memory type aligns with system requirements, as power loss will reset wiper positions. Check for any recent product discontinuation notices or lifecycle changes from Renesas.

Digital Potentiometers Selection Notes

Select this component when a dual-channel solution with I²C control is required. Ensure the 50 kOhm resistance value fits the circuit impedance constraints. Consider the volatile nature of the storage; if non-volatile retention is necessary, evaluate alternative models such as the ISL22343 series which offer EEPROM storage.

Digital Potentiometers Part Context

This part belongs to the XDCP™ family of digitally controlled potentiometers from Renesas. It serves as a solid-state replacement for mechanical potentiometers in applications requiring remote adjustment or automated calibration. The ISL23325 variant specifically provides dual channels in a compact footprint compared to single-channel counterparts.

Digital Potentiometers Replacement Considerations

For direct pin-compatible replacements with similar specifications, consider the ISL23325UFRUZ-TK. Verify that the package dimensions and electrical characteristics match the original design requirements before substitution.
