X9317WS8I

Digital Potentiometers Overview

The X9317WS8I 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 tap positions for precise adjustment. The device utilizes an Increment/Decrement control interface and incorporates non-volatile memory to retain the wiper setting upon power loss. It operates within a supply voltage range of 4.5 V to 5.5 V and is available in 8-pin packages including SOIC, MSOP, and TSSOP.

Digital Potentiometers Feature Summary

• 10 kOhm resistance with 100 discrete tap positions
• Increment/Decrement digital control interface
• Non-volatile memory retains wiper position after power cycle
• Single channel configuration in 8-lead package

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier biasing
• Voltage reference adjustment
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the manufacturer designation on the component marking, as the part may be labeled under Intersil or Renesas due to corporate acquisition history. Confirm the specific package variant (SOIC, MSOP, or TSSOP) matches the design footprint, as the base model number often refers to the family rather than a single physical package type.

Digital Potentiometers Selection Notes

Select this component when a linear taper potentiometer with 100 steps is required. Ensure the system logic supports Increment/Decrement signaling rather than SPI or I2C interfaces. Verify that the 5V nominal supply voltage aligns with the system's power rails, as the device is not rated for wider voltage ranges like 3.3V-only applications without checking absolute maximum ratings.

Digital Potentiometers Part Context

This component belongs to the X9317 series of digitally controlled potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance. The series is characterized by its non-volatile storage capability, distinguishing it from volatile digital pots that reset to zero on power-up.

Digital Potentiometers Replacement Considerations

Check for X9317 variants with different suffixes indicating package types (e.g., WS8 for SOIC, WM8 for MSOP). Cross-reference with X9116 series if fewer taps (16 vs 100) are acceptable, though interface protocols may differ.
