X9241AUVIZ

Digital Potentiometers Overview

The X9241AUVIZ is a quad digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers, each offering 64 tap positions with linear taper characteristics. The device features non-volatile memory to retain wiper settings and utilizes an I2C serial interface for control. It operates on a single 5V supply voltage within a 20-TSSOP package. Key electrical parameters include a resistance tolerance of ±20%, a typical temperature coefficient of ±300ppm/°C, and a contact resistance of 40 ohms. The component supports optional addressing and functions across a commercial temperature range.

Digital Potentiometers Feature Summary

• Quad configuration with 64 taps per potentiometer
• Non-volatile memory retains wiper position after power loss
• I2C serial interface with optional address selection
• Linear taper characteristic with ±20% resistance tolerance

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Instrumentation calibration systems

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as documentation indicates potential non-compliance in some variants. Confirm package dimensions match the 20-TSSOP specification (0.173 inch width). Check for obsolescence notices or PCN updates regarding label changes before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this part for applications requiring persistent setting storage without external EEPROMs. Ensure the I2C bus speed compatibility with the host controller. Verify that the 5V supply voltage aligns with the system power rails. Consider the ±20% tolerance if precise absolute resistance values are critical.

Digital Potentiometers Part Context

This component belongs to the X9241A family of digital potentiometers. It serves as a direct replacement for older Intersil versions of the same model number. The 'Z' suffix typically denotes RoHS compliance, although specific datasheet verification is required. It replaces legacy mechanical potentiometers in space-constrained PCB designs.

Digital Potentiometers Replacement Considerations

The X9241AUVI is listed as a direct substitute, though it may be obsolete. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
