X9251TS24IZ

Digital Potentiometers Overview

The X9251TS24IZ is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics Corporation, housed in a 24-lead SOIC package. It integrates four independent 100kΩ potentiometers, each featuring 256 linear taps for precise resistance adjustment. The device utilizes an SPI 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 single-supply configurations with VCC and V+ rails, offering low standby current consumption and high reliability for industrial applications.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 100kΩ potentiometers
• 256 linear taps per channel providing 0.4% resolution
• SPI serial interface for digital control and data transfer
• Nonvolatile storage retains wiper position for 100 years

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 'IZ' against official Renesas documentation to confirm industrial temperature rating (-40°C to +85°C) and RoHS compliance status. Confirm availability as the base X9251 series may have discontinued variants. Ensure the 24-SOIC package dimensions match the target PCB footprint requirements before procurement.

Digital Potentiometers Selection Notes

Select this component when four independent variable resistors are required in a single package. The 100kΩ resistance value suits moderate impedance circuits. Verify that the system operates within the 2.7V to 5.5V supply range. The SPI interface must be compatible with the host microcontroller's digital pins. Consider the ±20% tolerance if precise absolute resistance is critical without calibration.

Digital Potentiometers Part Context

This part belongs to the X9251 family of digitally controlled potentiometers. It is functionally similar to the X9250 but typically configured for single-supply operation compared to the dual-supply X9250. The TS24 designation indicates the 24-lead SOIC wide package. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include other X9251 variants with different suffixes indicating package or temperature changes. Cross-reference with X9250 series if dual-supply capability is needed instead of single-supply. Verify that substitute parts maintain the same 256-tap resolution and SPI command set compatibility.
