X9241AMSI

Digital Potentiometers Overview

The X9241AMSI is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers with resistance values of 2 kΩ, 10 kΩ, 10 kΩ, and 50 kΩ. Each potentiometer features 64 taps for linear adjustment and utilizes non-volatile memory to retain settings without power. The device operates on a single 5V supply and communicates via a serial interface. It is housed in a 20-pin SOIC package.

Digital Potentiometers Feature Summary

• Quad configuration with mixed resistance values: 2k, 10k, 10k, and 50k Ohms
• Non-volatile brush memory retains wiper position after power loss
• 64-tap resolution with linear taper for each potentiometer
• Serial (2-Wire) digital interface for control

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio circuits
• Calibration of sensor signals

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors. Check RoHS compliance status as older batches may differ. Confirm lead-free marking if required for assembly processes. Validate package integrity upon receipt due to moisture sensitivity classification.

Digital Potentiometers Selection Notes

Select this part when multiple independent variable resistors are needed in a compact form factor. Ensure the 64-step resolution meets the application's precision requirements. Verify that the serial interface timing matches the host controller capabilities. Consider the 5V operating voltage constraint for system compatibility.

Digital Potentiometers Part Context

This component belongs to the X9241A family of CMOS EEPOTs. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance. The series offers various resistance combinations and packaging options to suit different design constraints.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9241A variants with compatible pinouts. Verify that alternative parts maintain the same non-volatile memory characteristics and serial protocol compatibility before integration.
