X9241AWVI

Digital Potentiometers Overview

The X9241AWVI is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics Corporation. It integrates four independent 10 kΩ resistive elements with linear taper characteristics. Each potentiometer channel provides 64 discrete tap positions for precise resistance adjustment. The device utilizes non-volatile memory to retain wiper settings upon power loss and communicates via a two-wire serial interface. It operates on a single 5V supply voltage within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10 kΩ digital potentiometers
• Non-volatile EEPROM storage retains wiper position after power cycle
• Two-wire serial interface (I2C compatible) for control and data transfer
• Linear taper characteristic with 64 taps per channel

Digital Potentiometers Applications

• Programmable gain amplifiers in signal conditioning circuits
• Voltage reference trimming and calibration systems
• Audio volume control and equalization adjustments
• Industrial process control parameter setting

Digital Potentiometers Procurement Notes

Verify the specific suffix 'Z' or absence thereof against the manufacturer's current production status, as older variants may be obsolete. Confirm RoHS compliance requirements for the specific order code. Check moisture sensitivity level (MSL) ratings if lead-free soldering processes are required for assembly. Ensure the package type matches the PCB footprint design specifications.

Digital Potentiometers Selection Notes

Select this component when multiple independent analog resistance adjustments are needed in a compact surface-mount package. The 10 kΩ value suits moderate impedance applications, while the 64-tap resolution offers sufficient granularity for many control loops. Verify that the system voltage does not exceed the absolute maximum ratings and that the I2C bus speed is compatible with the device's timing constraints.

Digital Potentiometers Part Context

This part belongs to the X9241A family of CMOS EEPOTs, which also includes variants like the X9241AWSIZT1 and X9241AWV. These devices share the same core architecture but differ in packaging (SOIC vs TSSOP) and temperature grades. The X9241AWVI specifically denotes the SOIC-20 package variant designed for broader industrial operating temperatures compared to commercial grade options.

Digital Potentiometers Replacement Considerations

Direct substitutes include other members of the X9241A family such as the X9241AWSIZT1, provided the package and temperature range align with the design requirements. Cross-referencing with Intersil legacy parts may be necessary if sourcing from secondary markets, though Renesas is the primary manufacturer.
