X9317WS8T1

Digital Potentiometers Overview

The X9317WS8T1 is a single-channel Digitally Controlled Potentiometer (XDCP) manufactured by Intersil, now part of Renesas. It features a resistance value of 10 kOhms with 100 taps and utilizes a linear taper. The device incorporates non-volatile memory to retain the wiper setting upon power loss. It operates on a serial three-wire interface and functions within a supply voltage range of 4.5 V to 5.5 V. The component is housed in an 8-pin SOIC package and supports surface mount installation.

Digital Potentiometers Feature Summary

• Single channel digital potentiometer with 10 kOhm resistance and 100 taps
• Non-volatile memory retains wiper position after power cycle
• Serial 3-wire control interface for INCREMENT/DECREMENT operations
• Linear taper characteristic with low operating current of 50 uA

Digital Potentiometers Applications

• Audio volume control circuits requiring precise digital adjustment
• Calibration systems needing stable, non-volatile resistance settings
• Programmable gain amplifier configurations in signal processing
• Voltage reference trimming in measurement instrumentation

Digital Potentiometers Procurement Notes

Verify the manufacturer designation as Intersil or Renesas Electronics when sourcing this component. Confirm the specific suffix 'T1' indicates tape and reel packaging if required for automated assembly. Ensure compatibility with the 4.5 V to 5.5 V operating voltage range for your target application circuit design.

Digital Potentiometers Selection Notes

Select this component for applications requiring a single potentiometer with 100 discrete resistance steps. The non-volatile feature eliminates the need for external storage for the wiper position. Verify that the system interface supports the required serial protocol and that the 8-pin SOIC package fits the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9317 series of digitally controlled potentiometers. Variants in this family differ primarily in resistance values (e.g., 10k, 50k, 100k) and package types such as MSOP or TSSOP. The WS8 designation specifically identifies the 10kOhm version in the SOIC-8 package.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9317 variants with identical electrical characteristics but different packages, such as X9317TS8IZ or X9317MS8IZ. Cross-reference tools can identify parametrically similar parts from other manufacturers offering single-channel non-volatile digital potentiometers.
