X9241AUSZT1

Digital Potentiometers Overview

The X9241AUSZT1 is a quad digital potentiometer IC from Renesas Electronics, part of the XDCP series. It features four independent linear wiper controls with 64 taps each, offering a total resistance of 50 kOhms per channel. The device utilizes non-volatile memory to retain settings and communicates via a serial 2-wire I2C interface. Designed for surface mount installation in SOIC-20 packages, it operates on a single 5V supply within a commercial temperature range of 0°C to +70°C.

Digital Potentiometers Feature Summary

• Quad configuration with 64-tap resolution per potentiometer
• Non-volatile memory retains wiper position after power loss
• Serial 2-wire (I2C) compatible interface for control
• Linear taper characteristic with 50 kOhm resistance value

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify component status as the X9241AUSZT1 is listed as End-of-Life (EOL). Confirm availability through authorized distributors or secondary markets. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Validate that the SOIC-20 package dimensions match the target PCB footprint.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with non-volatile storage is required. Ensure the 50 kOhm resistance value fits the circuit design constraints. Verify compatibility with the system's I2C bus voltage levels. Consider the commercial temperature range (0°C to +70°C) against environmental conditions. Compare with the X9241AWSIZT1 if an extended industrial temperature range (-40°C to +85°C) is necessary.

Digital Potentiometers Part Context

This part belongs to the X9241A family of CMOS EEPROM-based digital potentiometers. It shares functional similarities with other variants like the X9241AYVZT1 (2kOhm) but differs in resistance value and package type. The 'U' suffix typically denotes the SOIC-20 package variant within the product line.

Digital Potentiometers Replacement Considerations

The X9241AWSIZT1 is a direct functional substitute with identical specifications except for an extended operating temperature range (-40°C to +85°C vs 0°C to +70°C). Both use the SOIC-20 package and maintain pin compatibility.
