X9317WM8Z-2.7

Digital Potentiometers Overview

The X9317WM8Z-2.7 is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics Corporation. It features a resistance value of 10 kOhms with 100 taps and utilizes non-volatile memory to retain wiper settings. The device operates on a serial 3-wire interface and supports power supply voltages ranging from 2.7 V to 5.5 V. Designed for surface-mount applications, it is housed in an MSOP-8 package and functions within a temperature range of 0°C to +70°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• Serial 3-wire interface for control
• Linear taper with 100 tap positions
• Single potentiometer configuration in MSOP-8 package

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in instrumentation circuits
• Voltage reference setting in data acquisition systems

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity handling requirements during storage and assembly. Ensure the specific suffix matches the required voltage range and package type for the target application.

Digital Potentiometers Selection Notes

Select this model for applications requiring a 10 kOhm resistance range with precise 100-step resolution. The 2.7V minimum operating voltage makes it suitable for low-power systems. Verify that the MSOP-8 footprint fits the PCB layout constraints and that the 3-wire serial interface is compatible with the host controller's available pins.

Digital Potentiometers Part Context

This component belongs to the X9317 family of CMOS digitally controlled potentiometers. Variants within this series differ primarily in resistance values (e.g., 1k, 10k, 50k, 100k), package types (MSOP, TSSOP, DIP), and operating temperature ranges. The WM8Z-2.7 designation specifically indicates the 10kOhm version in an MSOP-8 package with extended voltage support down to 2.7V.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9317 variants with identical pinouts and functionality but different resistance values or packages, such as X9317UM8Z-2.7 (50kOhm) or X9317WV8Z-2.7 (10kOhm in TSSOP). Cross-referencing datasheets is essential to ensure interface compatibility and electrical parameter alignment.
