X9258TS24Z-2.7

Digital Potentiometers Overview

The X9258TS24Z-2.7 is a quad digitally-controlled potentiometer (XDCP) from the Renesas X9258 series, housed in a 24-pin SOIC package. It integrates four independent linear potentiometers, each offering 256 tap positions with a resistance value of 50 kOhms and a tolerance of ±20%. The device utilizes a non-volatile memory architecture to retain wiper settings upon power loss. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and communicates via a standard I²C serial interface. The component supports optional addressing for multi-device systems and functions within an operating temperature range of 0°C to 70°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm digital potentiometers
• Non-volatile memory retains wiper position after power cycle
• I²C serial control interface with optional address selection
• 256 discrete tap positions per channel with linear taper

Digital Potentiometers Applications

• Programmable gain amplifiers in signal conditioning circuits
• Digital volume control in audio processing equipment
• Adjustable reference voltage generation in data acquisition systems
• Calibration of sensor bias and offset parameters

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' or 'Z' against the manufacturer's current datasheet to confirm packaging type (tape and reel vs. tube) and moisture sensitivity level. Confirm availability status as production lifecycles may vary by region. Ensure the I²C address pins are configured correctly for the target system topology before ordering.

Digital Potentiometers Selection Notes

Select this model when a quad-channel solution is required to save board space compared to single-potentiometer alternatives. The 50 kOhm resistance value is suitable for moderate impedance applications; verify that the contact resistance of approximately 150 Ohms meets the circuit's noise and accuracy requirements. Ensure the I²C bus speed is compatible with the device's maximum clock frequency specifications.

Digital Potentiometers Part Context

This component belongs to the X9258 family of quad XDCPs. Variants such as X9258US24Z differ primarily in packaging style (SOIC vs. TSSOP) or resistance values. The X9258 series is designed to replace mechanical potentiometers in environments requiring durability and programmability. It serves as a direct functional replacement for legacy Intersil parts with equivalent pinouts and electrical characteristics.

Digital Potentiometers Replacement Considerations

Check for X9258US24Z or X9258TS24IZ if different packaging or industrial temperature ranges are needed. Verify pin compatibility with existing footprints. Note that newer generations may have updated memory endurance specifications.
