X9317WPI-2.7

Digital Potentiometers Overview

The X9317WPI-2.7 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-PDIP package. It features a total resistance of 10 kOhms with 100 taps and linear taper characteristics. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates on a serial interface (U/D, INC, CS) and supports a supply voltage range of 2.7V to 5.5V. The component is rated for an operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• Single circuit configuration with 100 tap resolution
• Linear taper characteristic for precise resistance adjustment
• Serial control interface requiring only three pins

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming in measurement systems
• User interface parameter setting in embedded devices

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as older variants may not meet current environmental standards. Confirm package type matches design requirements, as DIP packages differ significantly from surface-mount options. Check for obsolescence notices from Renesas, as this model may be discontinued or superseded by newer revisions within the X9317 family.

Digital Potentiometers Selection Notes

Select this part when a through-hole solution is required for a 10k Ohm digital potentiometer. Ensure the application does not exceed the maximum current rating per tap. Verify that the serial interface timing meets the microcontroller's capabilities. Consider thermal dissipation if high currents are expected across the resistive element.

Digital Potentiometers Part Context

This component belongs to the X9317 family of CMOS digital potentiometers. It shares core functionality with other members like the X9317UV8IZ but differs in packaging (PDIP vs TSSOP/MSOP) and potentially manufacturing date codes. The '2.7' suffix typically indicates the minimum operating voltage capability.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9317 variants with identical electrical specifications but different packages, such as X9317WM8Z (MSOP) or X9317UV8IZ (TSSOP). Cross-reference with Intersil branded parts if sourcing from legacy distributors, as Renesas acquired Intersil's analog portfolio.
