X9317WM8

Digital Potentiometers Overview

The X9317WM8 is a single-channel digital potentiometer (XDCP) from the X9317 series, manufactured by Renesas Electronics under the Intersil brand. It features a linear resistance taper with 100 taps and a nominal resistance of 10 kOhms. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates via a serial 3-wire interface and supports supply voltages between 4.5 V and 5.5 V. Designed for surface-mount applications, it is housed in an MSOP-8 package and functions within a commercial temperature range of 0°C to +70°C.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 100 adjustable taps
• Non-volatile memory retains wiper position after power cycle
• Serial 3-wire control interface for simplified connectivity
• Linear resistance taper with 10 kOhm nominal value

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in instrumentation circuits
• Voltage reference trimming
• System calibration requiring persistent setting storage

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Check current production lifecycle status as availability may vary.

Digital Potentiometers Selection Notes

Select this model for applications requiring a single digital pot with 10 kOhm resistance and non-volatile storage. Ensure the operating voltage aligns with the 4.5 V to 5.5 V range. Consider the MSOP-8 package constraints for PCB layout. Verify temperature requirements against the 0°C to +70°C commercial grade specification.

Digital Potentiometers Part Context

This component belongs to the X9317 family of CMOS digitally controlled potentiometers originally developed by Xicor, which was acquired by Intersil in 2004. The product line is now managed by Renesas Electronics following subsequent corporate acquisitions. The X9317 series is characterized by its low power consumption and non-volatile architecture.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9317 variants such as X9317WM8IZ for industrial temperature ranges (-40°C to +85°C). Verify pin compatibility and interface protocols when substituting with other single-channel digital potentiometers.
