X9317WM8IZT1

Digital Potentiometers Overview

The X9317WM8IZT1 is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. 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 wiper settings without power. It operates on a serial 3-wire interface and supports a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 50 uA. The component is housed in an MSOP-8 package and is rated for an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• 10 kOhm total resistance with 100 discrete tap positions
• Non-volatile memory retains wiper position after power loss
• Serial 3-wire control interface (U/D, INC, CS)
• MSOP-8 surface mount package

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier biasing
• Voltage reference adjustment
• Calibration systems requiring persistent setting storage

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as datasheets may vary by production batch. Confirm the specific suffix 'IZ' indicates lead-free composition if required by assembly specifications. Check for End-of-Life notices or alternative part recommendations due to potential manufacturing phase-outs.

Digital Potentiometers Selection Notes

Select this component when a 10 kOhm resistance value and 100-step resolution are required. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Verify that the MSOP-8 footprint fits the PCB layout constraints compared to TSSOP alternatives.

Digital Potentiometers Part Context

This part belongs to the X9317 family of CMOS digitally controlled potentiometers. Variants within the family differ primarily in resistance values (e.g., 50 kOhm) and package types (e.g., TSSOP). The 'WM8' designation specifically identifies the 10 kOhm version in the MSOP-8 package.

Digital Potentiometers Replacement Considerations

Direct substitutes include X9317WM8IZ (tube packaging) or X9317UM8IZT1 (50 kOhm variant, requires circuit modification). Cross-brand equivalents like CAT5113ZI require verification of pinout and electrical parameter compatibility.
