X9317US8IZ

Digital Potentiometers Overview

The X9317US8IZ is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a 50 kΩ end-to-end resistance with a linear taper and 100 tap points for precise wiper positioning. The device utilizes a nonvolatile memory to store the wiper setting, ensuring data retention upon power-up. It operates on a single 5V supply with a typical standby current of less than 5 µA. The component is housed in an 8-SOIC surface-mount package and supports a 3-wire serial interface for control.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position after power loss
• 100 tap points with 50 kΩ linear resistance
• Low power consumption with <5 µA standby current
• Compatible with standard 3-wire serial interfaces

Digital Potentiometers Applications

• Voltage control circuits
• Current control applications
• Audio volume adjustment
• Gain control in instrumentation

Digital Potentiometers Procurement Notes

Verify the specific suffix 'US8IZ' against the manufacturer's datasheet to confirm the exact package dimensions and temperature range. Ensure compatibility with the target PCB footprint for the 8-SOIC form factor. Check for RoHS compliance status if required by local regulations.

Digital Potentiometers Selection Notes

Select this component when a nonvolatile digital potentiometer with 100 taps is required. The 50 kΩ resistance value suits moderate impedance applications. Verify that the system voltage aligns with the 5V nominal supply requirement and that the 3-wire interface matches the microcontroller or controller available.

Digital Potentiometers Part Context

This part belongs to the X9317 family of digitally controlled potentiometers. Variants within this family differ primarily in resistance values (10 kΩ, 50 kΩ, 100 kΩ) and package types such as TSSOP or MSOP. The US8IZ designation specifically identifies the 50 kΩ version in the SOIC-8 package.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9317 variants like X9317WM8IZ for different packages or resistance values. Ensure any substitute maintains the same nonvolatile memory feature and 3-wire interface protocol.
