X9241AWP

Digital Potentiometers Overview

The X9241AWP is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics (formerly Intersil). It integrates four independent 64-tap resistive elements with linear taper characteristics. The device operates on a single 5V supply and features non-volatile memory to retain wiper settings upon power loss. Communication is handled via a standard two-wire serial interface. Key electrical parameters include a nominal resistance of 10 kOhms, a maximum operating voltage of 5.5 V, and a typical supply current of 3 mA.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-tap digital potentiometers
• Non-volatile EEPROM storage retains wiper position after power cycle
• Two-wire serial interface for simplified microcontroller connection
• Linear taper resistance characteristic across all channels

Digital Potentiometers Applications

• Programmable gain amplifier circuits
• Voltage reference adjustment
• Digital volume control in audio systems
• Sensor biasing and calibration

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status for specific manufacturing lots. Check for End-of-Life (EOL) notices or Production Change Notices (PCN) that may affect long-term availability. Ensure proper handling for moisture-sensitive devices if packaged in tape and reel formats.

Digital Potentiometers Selection Notes

Select this part when a quad-channel solution is required to save board space compared to single-channel alternatives. Verify that the 10 kOhm resistance value matches the circuit design requirements. Ensure the system voltage stays within the 4.5 V to 5.5 V range. Consider the PDIP-20 package for through-hole mounting or SOIC/TSSOP variants for surface mount applications.

Digital Potentiometers Part Context

The X9241AWP belongs to the X9241A family of CMOS digital potentiometers. This series is designed to replace mechanical potentiometers in applications requiring programmable resistance. The 'W' suffix typically denotes a specific temperature grade or package variant within the broader X9241 product line.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements include other members of the X9241A family such as X9241AWSIZ or X9241AUPIZ, depending on the required resistance value and package type. Verify interface compatibility and memory retention features before substituting.
