X9317WS8IZ-2.7

Digital Potentiometers Overview

The X9317WS8IZ-2.7 is a single-channel digital potentiometer manufactured by Renesas Electronics Corporation, housed in an 8-SOIC surface-mount package. It features a total resistance of 10 kOhms with a linear taper and 100 tap positions for precise adjustment. The device utilizes non-volatile memory to retain the wiper setting upon power loss. It operates on a serial interface compatible with U/D, INC, and CS signals. The component supports a supply voltage range of 2.7V to 5.5V and functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 100-tap resolution with 10k Ohm total resistance
• Serial control interface (U/D, INC, CS)
• Wide operating voltage range: 2.7V to 5.5V

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• System calibration settings

Digital Potentiometers Procurement Notes

Verify the specific suffix '2.7' against official Renesas documentation to confirm the minimum operating voltage specification. Ensure the 8-SOIC package dimensions match the target PCB footprint. Confirm RoHS compliance status for the specific manufacturing lot prior to integration.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage of the resistance value is required without external battery backup. The 100-tap resolution offers finer granularity than standard 64-tap devices. Verify that the 10k Ohm resistance value aligns with the circuit's impedance requirements and that the serial interface timing meets the system controller's capabilities.

Digital Potentiometers Part Context

This part belongs to the XDCP™ series of digital potentiometers from Renesas. The X9317 model family provides single-potentiometer solutions with non-volatile memory. The WS8IZ designation indicates the 8-SOIC package variant with industrial temperature rating and specific voltage handling characteristics.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9317 variants such as X9317WM8IZ or X9317UV8IZ-2.7 if package changes are permissible. Verify pinout compatibility before substituting with different package types like TSSOP or MSOP.
