X9241AUP

Digital Potentiometers Overview

The X9241AUP is a quad digital potentiometer IC manufactured by Renesas Electronics Corporation, belonging to the XDCP series. It features four independent wipers with linear taper characteristics and 64 tap positions per circuit. The device utilizes non-volatile memory to retain resistance settings without power. Communication is handled via an I2C serial interface, supporting optional address selection for multi-device systems. The component operates on a single 5V supply and is housed in a 20-PDIP package. It exhibits a typical temperature coefficient of ±300ppm/°C and a contact resistance of 40Ω. The unit is currently obsolete.

• Linear taper characteristic

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifiers
• Voltage reference adjustment
• System calibration

Digital Potentiometers Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Renesas Electronics Corporation. Sourcing is limited to existing stock or surplus channels. Verification of authenticity is critical due to the high risk of counterfeit parts in the secondary market for discontinued semiconductors. Buyers should confirm the specific manufacturing date code and physical condition before acquisition.

Digital Potentiometers Selection Notes

Designers requiring this specific form factor must account for the discontinuation status. The primary alternative is the surface-mount variant X9241AUVI, which shares identical electrical specifications but requires PCB layout changes from through-hole to SMD. If through-hole mounting is mandatory, no direct active replacement exists within the same package type; redesigning for the UVIZ suffix or a different manufacturer's equivalent is necessary.

Digital Potentiometers Part Context

The X9241AUP is part of the broader X9241A family, which includes variants like the X9241AWSZ (SOIC-20) and X9241AUVI (TSSOP-20). All variants share the core quad digital potentiometer functionality. The UP suffix specifically denotes the 20-pin Plastic Dual In-Line Package (PDIP), distinguishing it from the SOIC and TSSOP options available in the same product line.

Digital Potentiometers Replacement Considerations

The X9241AUVIZ is listed as a direct substitute by the distributor, though it utilizes a 20-TSSOP surface-mount package rather than the through-hole PDIP format of the X9241AUP. Electrical parameters remain consistent, but mechanical integration requires adapter boards or PCB redesign.
