X9241AUSZ

Digital Potentiometers Overview

The X9241AUSZ is a quad digital potentiometer IC from the Renesas XDCP series, housed in a 20-pin SOIC package. It integrates four independent linear-taper potentiometers, each offering 64 tap positions and non-volatile memory for wiper position retention. The device operates on a single 5V supply with a resistance tolerance of ±20% and a typical temperature coefficient of ±300ppm/°C. Communication is handled via a serial two-wire interface, allowing for addressable control within a system.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50kΩ potentiometers
• Non-volatile EEPROM storage retains wiper settings after power loss
• Serial 2-wire interface supports optional addressing for multiple devices
• Linear taper characteristic with 64 discrete tap positions per channel

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Voltage reference trimming in measurement systems
• Audio volume control circuits utilizing digital interfaces
• Calibration networks for sensor signal conditioning

Digital Potentiometers Procurement Notes

Verify component status as this model may be discontinued or subject to limited availability. Confirm RoHS compliance details through official datasheets, as environmental declarations can vary by production batch. Ensure ordering suffixes match required packaging and temperature grades before procurement.

Digital Potentiometers Selection Notes

Select this part when a quad digital potentiometer with non-volatile memory is required. Verify that the 50kΩ resistance value fits the circuit impedance requirements. Check if the industrial temperature range (-40°C to +85°C) or commercial range (0°C to +70°C) aligns with the application environment, noting that the USZ suffix typically denotes specific package and temperature variants.

Digital Potentiometers Part Context

This component belongs to the X9241A family of CMOS digital potentiometers. It shares architectural similarities with other models like the X9241AWSIZT1 but differs in resistance value (50kΩ vs 10kΩ) and packaging. The series is characterized by its I2C-compatible serial interface and embedded EEPROM for persistent state management.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9241A variants with matching pinouts and functionality, such as the X9241AWSIZT1, provided resistance values and package types are compatible. Verify electrical specifications and temperature ranges when cross-referencing with alternative manufacturers' digital potentiometer ICs.
