X9241AMPIZ

Digital Potentiometers Overview

The X9241AMPIZ is a quad digitally controlled potentiometer (XDCP) manufactured by Intersil, now part of Renesas Electronics. It integrates four independent potentiometers within a single monolithic CMOS microcircuit, each featuring 63 resistive elements and 64 tap positions. The device utilizes a 2-wire serial interface for wiper position control and includes nonvolatile memory to retain settings. Key electrical parameters include a 5V operating supply voltage, 3mA typical current consumption, and linear taper resistance options available in the family. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 20-pin PDIP package.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-tap potentiometers per package
• Nonvolatile memory retains wiper position data for up to 100 years
• 2-wire serial interface allows direct read/write/transfer of wiper positions
• Low power CMOS technology with 3mA typical operating current

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Hardware parameter adjustments in industrial control systems
• Signal processing circuits needing digital calibration
• Voltage reference trimming in measurement equipment

Digital Potentiometers Procurement Notes

Verify component authenticity as the X9241A series has reached end-of-life status. Check manufacturer documentation for specific lot traceability and ensure compliance with RoHS directives if required for the target application. Confirm package integrity upon receipt due to age-related handling risks.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with nonvolatile storage is required. Ensure the system supports a 2-wire serial bus protocol. Verify that the 5V supply voltage aligns with the design constraints. Consider alternative packages like SOIC or TSSOP if surface mount technology is preferred over through-hole DIP.

Digital Potentiometers Part Context

The X9241A belongs to the XDCP™ family of digitally controlled potentiometers. This series is designed to replace mechanical potentiometers in applications requiring remote adjustment or automated calibration. The 'M' suffix typically denotes a specific resistance value variant within the quad channel lineup, often involving mixed values such as 2kΩ, 10kΩ, and 50kΩ combinations across the four channels.

Digital Potentiometers Replacement Considerations

Direct replacements may be limited due to the EOL status. Review datasheets for compatible quad XDCPs from Renesas or other manufacturers supporting 2-wire interfaces and similar pinouts. Validate electrical specifications and package dimensions before substitution.
