X9241AWPIZ

Digital Potentiometers Overview

The X9241AWPIZ is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent potentiometers with a resistance value of 10 kOhms and 64 taps each. The device utilizes non-volatile EEPROM memory to retain wiper settings upon power loss. Communication is handled via a serial 2-wire interface, operating on a single 5 V supply voltage with a maximum current consumption of 3 mA. It is housed in a 20-pin PDIP package designed for through-hole PCB mounting.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10 kOhm potentiometers
• Non-volatile EEPROM storage retains wiper position after power cycle
• Serial 2-wire interface for control and data transfer
• Linear taper with 64 tap positions per potentiometer

Digital Potentiometers Applications

• Programmable gain amplifier circuits
• Voltage reference adjustment
• System calibration and trimming

Digital Potentiometers Procurement Notes

The X9241AWPIZ is listed as an obsolete or discontinued product by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct factory orders. Buyers must confirm the specific revision level and RoHS compliance status, as legacy stock may vary in environmental certification compared to newer replacements.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with non-volatile memory and a 10 kOhm range is required. Ensure the design supports the 2-wire serial interface protocol. Verify that the 20-PDIP through-hole package fits the board layout constraints. Compare against the X9241AWSIZT1 if surface mount technology (SOIC-20) is preferred instead of through-hole packaging.

Digital Potentiometers Part Context

This part belongs to the X9241A family of CMOS digital potentiometers. It shares core architectural features with other variants like the X9241AYPZ (2 kOhm) and X9241AWVZ (10 kOhm TSSOP). The 'W' suffix typically denotes the 10 kOhm resistance value, while 'PIZ' indicates the PDIP package and lead-free/RoHS compliant construction.

Digital Potentiometers Replacement Considerations

Direct replacement options include the X9241AWSIZT1 for surface mount applications or the X9241AWVZ for alternative thin packages. For through-hole requirements, verify compatibility with the X9241AYPZ if lower resistance values are acceptable.
