X9314WS

Digital Potentiometers Overview

The X9314WS is a single digitally controlled potentiometer (XDCP) manufactured by Intersil, now part of Renesas. It features a solid-state nonvolatile design with 32 taps and a logarithmic resistance taper. The end-to-end resistance is 10 kΩ with a typical wiper resistance of 40 Ω. The device operates within a supply voltage range of 3.0 V to 5.5 V and draws a maximum standby current of 500 µA. It utilizes a three-wire up/down serial interface for control and includes nonvolatile memory to store and recall the wiper position upon power-up.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 32 resistive taps
• Logarithmic resistance taper with 10 kΩ total resistance
• Nonvolatile memory retains wiper position after power loss
• Three-wire serial interface (CS, U/D, INC) for control

Digital Potentiometers Applications

• Digitally controlled resistance trimming in audio circuits
• Parameter adjustment in signal processing systems
• Volume control applications requiring logarithmic response

Digital Potentiometers Procurement Notes

Verify the manufacturer designation, as the component was originally produced by Intersil and is now managed by Renesas Electronics. Confirm the specific package variant, as the X9314 series is available in both MSOP-8 and SOIC-8 configurations. Ensure the logarithmic taper specification matches the application requirements, as linear variants exist within the same family.

Digital Potentiometers Selection Notes

Select this component when a nonvolatile digital potentiometer with logarithmic characteristics is required. The 10 kΩ resistance value and 32 tap resolution are suitable for precision adjustment tasks. Verify that the operating voltage falls within the 3.0 V to 5.5 V range and that the interface logic levels are compatible with the controlling microcontroller or system bus.

Digital Potentiometers Part Context

The X9314WS belongs to the X9314 family of single-channel digitally controlled potentiometers. This series is designed to replace mechanical potentiometers in applications requiring digital adjustment and data retention. The 'WS' suffix typically denotes the SOIC-8 package option, distinguishing it from the MSOP-8 variant found in other part numbers like X9314WMIZ.

Digital Potentiometers Replacement Considerations

Direct replacements include other parts from the X9314 family, such as the X9314WS-3 or X9314WSZ, which share identical electrical specifications and pinouts. When substituting, ensure the replacement maintains the logarithmic taper and nonvolatile memory functionality.
