X9258US24I-2.7T1

Digital Potentiometers Overview

The X9258US24I-2.7T1 is a quad digital potentiometer from the Renesas XDCP series, housed in a 24-pin SOIC package. It features four independent wiper circuits with 256 tap positions and a nominal resistance of 50 kΩ per circuit. The device operates on a single supply voltage ranging from ±2.7V to 5.5V and utilizes an I²C serial interface for control. It incorporates non-volatile memory to retain settings without power. Key electrical parameters include a tolerance of ±20%, a temperature coefficient of ±300ppm/°C, and a contact resistance of 150 Ω. The component supports optional addressing and functions within an operating temperature range of -40°C to 85°C.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as older variants may differ. Check lead times due to potential end-of-life status or obsolescence notices associated with this part number family. Ensure the I²C address configuration matches system requirements.

Digital Potentiometers Selection Notes

Select this component for applications requiring multiple independent analog adjustments controlled digitally via I²C. The 50kΩ value suits moderate impedance circuits. Verify that the ±20% tolerance meets system accuracy needs. Consider the 256-step resolution for required granularity. Ensure the operating temperature range covers the intended environment.

Digital Potentiometers Part Context

This part belongs to the X9258 family of quad digital potentiometers. Variants like X9258US24IZ offer similar functionality but may differ in packaging (e.g., TSSOP) or environmental ratings. The 'I' suffix typically denotes industrial temperature range. The 'T1' suffix specifies reel packaging. This model represents a legacy component in the XDCP line.

Digital Potentiometers Replacement Considerations

Direct substitutes include X9258US24IZ for pin-compatible replacement. Cross-reference with other X9258 variants if packaging differences are acceptable. Verify functional equivalence regarding I²C protocol and memory retention before substitution.
