X9250US24IZ-2.7T1

Digital Potentiometers Overview

The X9250US24IZ-2.7T1 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers, each featuring 256 resistor taps for 0.4% resolution, within a single monolithic CMOS integrated circuit. The device utilizes a 3-wire SPI serial interface for wiper position control and includes nonvolatile memory to retain settings. Each channel offers a volatile Wiper Counter Register and four nonvolatile Data Registers. The component supports supply voltages ranging from 2.7V to 5.5V and operates within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Integrates four 50kΩ potentiometers with 256 taps per channel
• SPI serial control interface with nonvolatile data retention
• Low standby current consumption of less than 5µA maximum
• Dual supply capability: V+ and VCC from 2.7V to 5.5V, V– from -2.7V to -5.5V

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing applications requiring variable resistance
• Industrial systems needing nonvolatile gain or offset adjustments

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) and 'Z' denotes RoHS compliance. Confirm the 'T1' suffix corresponds to the tape and reel packaging format required for automated assembly processes. Cross-reference the manufacturer part number with official Renesas documentation to ensure compatibility with system voltage requirements.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with SPI interface and nonvolatile storage is required. Ensure the 50kΩ total resistance and linear taper match the circuit design. Verify that the 256-tap resolution provides sufficient granularity for the application. Check that the operating environment falls within the specified -40°C to +85°C temperature range.

Digital Potentiometers Part Context

This part belongs to the X9250 family of Quad Digitally Controlled Potentiometers. It shares core architecture with variants like the X9250US24I-2.7T1 but differs in package type and environmental rating. The US24 designation specifies the 24-lead SOIC plastic package. The series is designed for low-noise and low-power applications compared to older digital potentiometer technologies.

Digital Potentiometers Replacement Considerations

The X9250US24IZ-2.7T1 is functionally compatible with the X9250US24I-2.7T1 regarding electrical performance. Substitution requires verifying that the replacement part maintains the same SOIC-24 package dimensions and pinout configuration.
