X9250TS24Z-2.7

Digital Potentiometers Overview

The X9250TS24Z-2.7 is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics, integrating four independent potentiometers on a monolithic CMOS IC. Each channel features 256 resistor taps for linear adjustment and utilizes nonvolatile memory to retain wiper positions. The device operates with supply voltages ranging from 2.7V to 5.5V for VCC and V+, and -2.7V to -5.5V for V-. It employs an SPI serial interface for control and offers low standby current. The component is housed in a 24-lead SOIC package.

Digital Potentiometers Feature Summary

• Integrates four 100kΩ digitally controlled potentiometers with 256 taps each
• Nonvolatile data registers (DR0-DR3) per pot retain settings without power
• SPI serial interface for wiper position control and register access
• Dual supply capability: VCC/V+ (2.7V–5.5V) and V- (-2.7V to -5.5V)

Digital Potentiometers Applications

• Industrial control systems requiring precise parameter adjustments
• Signal processing circuits needing programmable gain or attenuation
• Calibration equipment utilizing stable digital resistance values

Digital Potentiometers Procurement Notes

Verify the specific suffix '-2.7' against official Renesas documentation to confirm voltage range and pinout compatibility. Ensure RoHS compliance status matches project requirements, as manufacturing updates may affect environmental declarations. Confirm package dimensions against the 24-SOIC specification before integration.

Digital Potentiometers Selection Notes

Select this component when four independent, nonvolatile digital potentiometers are required in a single package. The 256-tap resolution provides approximately 0.4% step accuracy. Verify that the system supports SPI communication and that the dual-supply voltage ranges align with the application's power rails. Consider thermal dissipation if operating near maximum temperature limits.

Digital Potentiometers Part Context

This part belongs to the X9250 series of Quad Digitally Controlled Potentiometers. It is functionally similar to the X9251 but differs in supply voltage specifications. The 'TS24' indicates a 24-lead SOIC package, while 'Z' typically denotes lead-free/RoHS compliance. The '-2.7' suffix specifies the minimum operating voltage threshold.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9250 variants such as X9250TS24Z. Cross-model replacements like the X9251 require verification of supply voltage compatibility, as the X9251 may have different electrical characteristics regarding V- rail operation.
