ISL23325UFRUZ-T7A

Digital Potentiometers Overview

The ISL23325UFRUZ-T7A is a dual-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features two independent potentiometers, each with 256 tap positions and a resistance value of 50 kOhms. The device utilizes a volatile memory type for wiper position storage and communicates via an I²C serial interface. It operates within a supply voltage range of 1.2V to 5.5V (or 1.7V to 5.5V depending on specific configuration) and supports selectable addresses. The component is housed in a 16-UTQFN package measuring 2.6x1.8 mm and is rated for operation between -40°C and +125°C.

Digital Potentiometers Feature Summary

• Dual-channel configuration with 256 taps per potentiometer
• I²C serial interface with selectable address capability
• Volatile wiper memory retaining settings during power cycles
• Linear taper with ±20% tolerance and 65ppm/°C temperature coefficient

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Voltage reference trimming in precision measurement systems
• Audio volume control circuits with digital interface requirements

Digital Potentiometers Procurement Notes

Verify current availability status as the component may be subject to limited supply or obsolescence notices. Confirm package integrity and RoHS compliance through official datasheets before integration. Check for end-of-life announcements from Renesas Electronics to ensure long-term project viability.

Digital Potentiometers Selection Notes

Select this part for applications requiring dual independent digital pots with I²C control. Ensure system voltage aligns with the 1.2V–5.5V operating range. Consider the volatile memory characteristic if non-volatile retention is required, as alternative models may be necessary for such use cases.

Digital Potentiometers Part Context

This component belongs to the ISL23325 family of digital potentiometers. It shares functional similarities with other XDCP series devices but is distinct in its dual-channel architecture and 16-pin UTQFN packaging. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.
