X9250TV24I

Digital Potentiometers Overview

The X9250TV24I is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers within a single monolithic CMOS integrated circuit, each featuring 256 resistor taps for 0.4% resolution. The device utilizes a serial peripheral interface (SPI) to control wiper positions via volatile Wiper Counter Registers and nonvolatile Data Registers. It supports dual power supplies ranging from ±2.7V to ±5.5V or a single supply of 2.7V to 5.5V. The component is housed in a 24-pin Thin Shrink Small Outline Package (TSSOP) with a width of 4.40mm.

Digital Potentiometers Feature Summary

• Integrates four 100kΩ potentiometers with linear taper and 256 taps per channel
• Nonvolatile memory retains wiper position data for up to 100 years
• Operates on dual supplies (±2.7V to ±5.5V) or single supply (2.7V to 5.5V)
• Low standby current consumption of less than 5µA maximum

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing applications requiring variable resistance
• System calibration and gain adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' indicates an industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm package dimensions match the 24-TSSOP specification (7.8 x 4.4 x 0.90 mm). Check RoHS compliance status as older manufacturing lots may differ from current production standards.

Digital Potentiometers Selection Notes

Select this component when four independent digital potentiometers are required in a compact surface-mount footprint. Ensure the system voltage falls within the 2.7V to 5.5V range. Verify that the SPI interface timing requirements of the host microcontroller are compatible with the device's serial control interface specifications.

Digital Potentiometers Part Context

The X9250 belongs to the XDCP™ family of low noise, low power digitally controlled potentiometers. It serves as a direct replacement for legacy analog potentiometers in applications requiring programmable resistance. The TV24 suffix specifically denotes the 100kΩ resistance value and the 24-lead TSSOP package configuration.

Digital Potentiometers Replacement Considerations

Cross-reference with X9250US24 for SOIC package alternatives or X9250UV24IZ for different resistance values. Verify pin compatibility and electrical parameters before substituting with other quad digital potentiometer models.
