X9317US8Z-2.7T1

Digital Potentiometers Overview

The X9317US8Z-2.7T1 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-SOIC surface-mount package. It features a resistance value of 10 kOhms with 100 taps and linear taper characteristics. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes a non-volatile memory architecture to retain wiper settings upon power loss. Control is managed via a standard 3-wire serial interface (Up/Down, Inc, CS). Key electrical parameters include a ±20% resistance tolerance and a typical temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 100-tap resolution with linear taper for precise adjustment
• Low power consumption with 50 µA operating current
• Compatible with standard 3-wire serial control interfaces

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• System calibration and offset correction

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as suffix variations may indicate different environmental certifications. Confirm package type matches design requirements, as 'SOIC' variants differ physically from TSSOP versions within the same family. Check for obsolescence notices or PCNs regarding manufacturing site changes before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage is required for analog settings without external EEPROMs. Ensure the 10kOhm resistance value aligns with circuit impedance requirements. Verify that the 3-wire interface signals are available on the controlling microcontroller. Consider the -40°C to +85°C industrial temperature range if operating in harsh environments.

Digital Potentiometers Part Context

This part belongs to the X9317 family of CMOS digital potentiometers. It shares core functionality with other variants like the X9317UV8Z but differs in resistance value and physical packaging. The 'Z' suffix typically denotes lead-free/RoHS compliant construction, while 'T1' indicates tape-and-reel packaging for automated assembly.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9317 series parts with matching resistance and package, such as X9317WS8Z-2.7T1 (same SOIC package, 10kOhm). Cross-package replacements require mechanical redesign. Verify pinout compatibility when substituting with similar digital potentiometers from other manufacturers.
