X9241AMSZT1

Digital Potentiometers Overview

The X9241AMSZT1 is a quad CMOS electrically erasable potentiometer (EEPOT) manufactured by Renesas Electronics. It integrates four independent digital potentiometers with non-volatile memory, offering resistance values of 2 kΩ, 10 kΩ, and 50 kΩ. The device features 64 taps per potentiometer and utilizes a linear taper. It operates on a single 5 V supply with a maximum current consumption of 3 mA. Communication is handled via a serial 2-wire interface. The component is housed in a 20-lead SOIC package and is rated for an operating temperature range of 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 loss
• Serial 2-wire interface for simplified control connections
• Available in 2 kΩ, 10 kΩ, and 50 kΩ resistance options

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio systems

Digital Potentiometers Procurement Notes

The X9241AMSZT1 is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and distributors may not stock this specific part number. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with non-volatile storage is needed. Ensure the application supports the 2-wire serial interface and operates within the 4.5 V to 5.5 V supply range. Verify that the 0°C to +70°C commercial temperature range meets environmental requirements.

Digital Potentiometers Part Context

This part belongs to the X9241A series of quad EEPROM-based digital potentiometers. It shares architectural similarities with other members like the X9241AWSIZT1 but differs in packaging (SOIC vs. TSSOP) and temperature rating. The suffix 'AMS' indicates the specific resistance variant and package type within the family.

Digital Potentiometers Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider evaluating the X9241AWSIZT1 for similar functionality in an SOIC-20 package with extended temperature range, or consult Renesas for updated portfolio recommendations.
