X9258US24I

Digital Potentiometers Overview

The X9258US24I is a discontinued quad digital potentiometer from the XDCP series by Renesas Electronics. It features four independent wipers, each with 256 taps and a resistance of 50 kOhms. The device utilizes an I2C serial interface for control and includes non-volatile memory to retain settings. It operates within a supply voltage range of ±5V and supports optional addressing. The component is housed in a 24-SOIC package and exhibits a linear taper with a typical temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Quad configuration with 256-tap resolution per channel
• Non-volatile memory storage for wiper positions
• I2C serial control interface with optional address capability
• Linear resistance taper and 50 kOhm nominal value

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

This specific part number is marked as obsolete and no longer manufactured. Verification of availability should focus on the direct replacement X9258US24IZ, which maintains identical electrical specifications but complies with RoHS3 standards. Sourcing requires checking for surplus stock or alternative packages such as the TSSOP variant if pin compatibility allows.

Digital Potentiometers Selection Notes

Designers requiring current production units must select the X9258US24IZ suffix instead. The original US24I version lacks RoHS compliance compared to the Z suffix variant. Ensure that the system design accounts for the ±20% resistance tolerance and the 40 Ohm contact resistance typical values when calculating circuit precision requirements.

Digital Potentiometers Part Context

The X9258 belongs to the X9258 family of quad digital potentiometers. It shares core architecture with variants like the X9258US24IZ and the wider X9258 series, differing primarily in packaging, environmental compliance status, and manufacturing lifecycle stage. It serves as a solid-state alternative to mechanical potentiometers in space-constrained applications.

Digital Potentiometers Replacement Considerations

The confirmed direct substitute is X9258US24IZ. This replacement offers the same functional parameters while meeting RoHS3 regulations. No other cross-model substitutes are verified for this specific package and specification combination.
