X9250UV24IZ-2.7

Digital Potentiometers Overview

The X9250UV24IZ-2.7 is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics, integrating four independent potentiometers on a single monolithic CMOS IC. It features 256 resistor taps per channel with linear taper and offers selectable resistance values of 50 kΩ or 100 kΩ. The device utilizes an SPI serial interface for wiper position control and includes nonvolatile memory to retain settings across power cycles. Operating within a supply voltage range of 2.7 V to 5.5 V, it supports dual-supply configurations down to -5.5 V. Packaged in a 24-pin TSSOP, it is designed for applications requiring precise parameter adjustments and signal processing.

Digital Potentiometers Feature Summary

• Integrates four independent 256-tap digitally controlled potentiometers with linear taper.
• SPI serial interface allows direct reading and writing of volatile Wiper Counter Registers and nonvolatile Data Registers.
• Nonvolatile storage retains wiper positions for up to 100 years with endurance of 100,000 data changes per bit.
• Low standby current consumption of less than 5 µA maximum for the total package.

Digital Potentiometers Applications

• Control systems requiring precise parameter adjustments.
• Signal processing circuits needing variable resistance configuration.
• Audio equipment for gain or tone control adjustments.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to production timelines. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Digital Potentiometers Selection Notes

Select this model when four independent digital pots are required in a compact surface-mount package. Verify that the system interface supports SPI communication and that the 256-tap resolution meets the application's precision requirements. Consider the 50 kΩ or 100 kΩ resistance options based on circuit impedance needs.

Digital Potentiometers Part Context

This component belongs to the X9250 series of quad digitally controlled potentiometers. It shares functional similarities with other members like the X9258 and X9259 but differs in interface type and pinout configuration. The UV24 suffix indicates the 24-lead TSSOP package variant suitable for space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct replacements may include other quad digital potentiometers from the same family, such as the X9258UV24IZ, provided the interface compatibility and pinout match. Verify electrical specifications and package dimensions before substitution.
