X9241AMSIZT1

Digital Potentiometers Overview

The X9241AMSIZT1 is a quad CMOS digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent potentiometers with non-volatile memory to retain wiper settings upon power loss. Each potentiometer offers 64 taps and linear taper characteristics. The device operates on a single 5V supply (4.5V to 5.5V) with a typical current consumption of 3mA. It features a serial 2-wire interface for control and is housed in a 20-lead SOIC package. The component supports an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-tap digital potentiometers

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly. Validate that the specific suffix corresponds to the required package and temperature grade.

Digital Potentiometers Selection Notes

Select this part when a quad digital potentiometer with non-volatile storage is required. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Verify that the 64-step resolution meets the application's precision needs. Consider the SOIC-20 package dimensions for PCB layout compatibility.

Digital Potentiometers Part Context

This component belongs to the X9241A family of quad digital potentiometers. Variants within the series differ primarily by resistance value (e.g., 2kΩ, 10kΩ, 50kΩ), package type (SOIC vs TSSOP), and temperature rating (Industrial vs Automotive). The AMSI suffix indicates the specific combination of resistance, package, and temperature grade for this unit.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9241A variants with matching pinouts and electrical specifications. Verify that substitute parts maintain the same non-volatile memory functionality and serial interface protocol. Cross-reference package dimensions if mechanical constraints are critical.
