X9259UV24IZ

Digital Potentiometers Overview

The X9259UV24IZ is a digital potentiometer manufactured by Renesas Electronics Corporation. It features a single wiper configuration with 256 tap positions, providing precise resistance adjustment capabilities. The device operates within a supply voltage range of 2.7V to 5.5V and utilizes an I2C-compatible serial interface for control. It includes non-volatile memory to retain the wiper setting upon power cycle, ensuring data integrity without external backup. The component is housed in a compact 8-lead SOIC package, suitable for space-constrained applications requiring reliable analog signal conditioning.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IZ' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with I2C bus protocols used in the target system. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer before procurement planning.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with non-volatile storage is required. Confirm that the 256-step resolution meets the application's precision needs. Verify that the I2C address conflicts are managed within the system design. Consider the operating temperature range specified in the datasheet relative to the environmental conditions.

Digital Potentiometers Part Context

This part belongs to the X9259 family of digital potentiometers. It shares core functionality with other variants but differs in package and potentially temperature rating due to the 'IZ' suffix. It serves as a solid-state alternative to mechanical potentiometers in systems requiring programmable resistance values.

Digital Potentiometers Replacement Considerations

Check for direct pin-to-pin replacements within the X9259 series with different suffixes. Verify functional equivalence if substituting with similar digital potentiometers from other manufacturers, focusing on I2C compatibility and voltage ranges.
