X9241AMSZ

Digital Potentiometers Overview

The X9241AMSZ is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent potentiometers with linear taper and non-volatile memory to retain wiper settings upon power loss. Each potentiometer offers 64 taps for resistance adjustment. The device operates on a single 5V supply with a maximum voltage of 5.5V and draws 3mA of operating current. It features a serial 2-wire interface for control and is housed in a 20-lead SOIC package.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10k Ohm potentiometers
• Non-volatile EEPROM storage retains wiper position after power cycle
• 64-tap resolution per channel with linear taper
• Serial 2-wire interface for simplified connectivity

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• System calibration and offset correction

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Check RoHS compliance status via official datasheets. Confirm lead time and availability directly with suppliers since stock levels fluctuate. Ensure proper handling for moisture-sensitive devices during storage and reflow soldering processes.

Digital Potentiometers Selection Notes

Select this component when multiple independent variable resistors are required in a compact surface-mount package. The 10k Ohm value suits moderate impedance applications. Verify that the 64-step resolution meets precision requirements. Consider the 2-wire interface compatibility with existing microcontroller GPIO pins before integration.

Digital Potentiometers Part Context

Part of the X9241A family of CMOS EEPOTs. Similar variants include X9241AWSZ (SOIC-20) and X9241AWVZ (TSSOP-20). The AMSZ suffix denotes the specific SOIC-20 package variant within the broader X9241A product line designed for general-purpose analog control applications.

Digital Potentiometers Replacement Considerations

Direct pin-compatible alternatives within the same series include X9241AWSZ. Cross-reference electrical specifications such as resistance tolerance and temperature coefficient when substituting. Verify package dimensions match PCB footprint requirements.
