X9258TS24I-2.7T1

Digital Potentiometers Overview

The X9258TS24I-2.7T1 is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics, housed in a 24-pin TSSOP package. It integrates four independent 50kΩ potentiometers, each featuring 256 taps for precise resistance adjustment. The device utilizes an I²C serial interface for control and includes nonvolatile memory to retain wiper positions across power cycles. Operating within a supply voltage range of 2.7V to 5.5V, it supports industrial temperatures from -40°C to +85°C with a linear taper and ±20% resistance tolerance.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50kΩ potentiometers

• I²C serial control interface with optional addressing
• Nonvolatile data registers for wiper position retention

Digital Potentiometers Applications

• Industrial process control parameter adjustments
• Signal processing circuit calibration
• Programmable gain amplifier settings
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status for this specific variant, as earlier versions may differ. Ensure the I²C address configuration matches system requirements before procurement.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with I²C control is required. The 50kΩ resistance value suits moderate impedance applications. Verify that the 2.7V minimum supply voltage aligns with the system's power rails. The TSSOP package requires appropriate PCB footprint design for thermal management.

Digital Potentiometers Part Context

This part belongs to the X9258 series of quad digitally controlled potentiometers. It shares functional similarities with the X9250 but differs in its I²C interface compared to the SPI-based X9250. The 'TS' indicates the TSSOP package, while 'I' denotes the industrial temperature range.

Digital Potentiometers Replacement Considerations

Direct replacement options include other X9258 variants with compatible packages and interfaces. Verify pinout compatibility and electrical parameters such as wiper resistance and supply voltage ranges when substituting.
