X9241AMSIT2

Digital Potentiometers Overview

The X9241AMSIT2 is a quad CMOS electrically erasable potentiometer (EEPOT) manufactured by Renesas Electronics. It integrates four independent digital potentiometers within a single SOIC-20 package. Each channel provides 64 tap positions with linear taper characteristics and non-volatile memory to retain wiper settings upon power loss. The device operates on a single 5V supply, drawing approximately 3mA of current. It utilizes a standard 2-wire serial interface for control. The component is rated for commercial temperature ranges from 0°C to +70°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 64-tap digital potentiometers
• Non-volatile memory retains wiper position after power cycle
• Linear resistance taper across 2kΩ, 10kΩ, or 50kΩ options
• 2-wire serial interface compatible with standard microcontrollers

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Instrumentation calibration

Digital Potentiometers Procurement Notes

Verify the specific resistance value suffix (e.g., A for 2k, B for 10k, C for 50k) as the base model number covers multiple variants. Confirm the 'IT2' tape and reel packaging designation against current distributor listings. Check RoHS compliance status and moisture sensitivity level requirements before procurement.

Digital Potentiometers Selection Notes

Select this component when a compact solution for multiple variable resistors is required without mechanical wear. 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 requirements compared to higher-resolution alternatives.

Digital Potentiometers Part Context

This part belongs to the X9241A series of quad EEPOTs. It shares architectural similarities with other members like the X9241AWSIZ but differs in package type and temperature rating. The series is designed to replace mechanical potentiometers in space-constrained PCB designs.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other X9241A variants such as X9241AWSIZ or X9241AMSZT1, provided the resistance value and temperature grade match the design requirements. Cross-reference datasheets for interface timing compatibility.
