X9317US8Z

Digital Potentiometers Overview

The X9317US8Z is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single circuit with 100 tap points and a total end-to-end resistance of 50 kΩ. The device utilizes a nonvolatile memory to store wiper positions, allowing recall upon power-up. It operates on a single supply voltage ranging from 2.7 V to 5.5 V, with a typical standby current of less than 5 µA. The component employs a 3-wire serial interface (Up/Down, Increment, Chip Select) for control and is housed in an 8-SOIC package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position data for 100 years without power
• 100 discrete wiper tap points with linear resistance taper
• Low power consumption with standby current under 5 µA
• Operates within a supply voltage range of 2.7 V to 5.5 V

Digital Potentiometers Applications

• Voltage control circuits requiring adjustable resistance
• Current control applications using variable resistor configurations
• Systems requiring persistent setting retention after power cycles

Digital Potentiometers Procurement Notes

Verify the specific suffix 'US8Z' against the manufacturer's datasheet to confirm the 8-SOIC package and commercial temperature range specifications. Ensure compatibility with the required 50 kΩ resistance value and 3-wire interface logic levels before integration into the design.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with 50 kΩ resistance and surface-mount SOIC packaging is required. Consider the 100-tap resolution and nonvolatile storage capabilities if application settings must persist across power cycles. Verify that the operating temperature range of 0°C to 70°C meets the environmental requirements of the target system.

Digital Potentiometers Part Context

The X9317US8Z belongs to the X9317 series of Digitally Controlled Potentiometers (XDCP). This family offers solid-state alternatives to mechanical potentiometers, providing high reliability and endurance with up to 100,000 data changes per bit register. The series includes variants with different resistance values and packages.

Digital Potentiometers Replacement Considerations

Check for other suffixes in the X9317 series, such as X9317WM8Z or X9317UV8Z, which may offer different resistance values or package types like MSOP or TSSOP while maintaining similar electrical characteristics.
