X9317UV8IZT1

Digital Potentiometers Overview

The X9317UV8IZT1 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-TSSOP surface-mount package. It features a total resistance of 50 kOhms with 100 tap positions and linear taper characteristics. The device operates on a 5V supply voltage within a range of 4.5V to 5.5V, consuming 50 uA of current. It utilizes non-volatile memory to retain settings and communicates via a serial interface supporting U/D, INC, and CS signals. The component is rated for industrial temperatures between -40°C and +85°C, with a typical temperature coefficient of ±300ppm/°C and contact resistance of 200 Ohms.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• Serial control interface (U/D, INC, CS) for simple integration
• Linear taper with 100 discrete tap positions
• Industrial operating temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio circuits

Digital Potentiometers Procurement Notes

Verify RoHS3 compliance status as datasheets indicate conformity, while older variants may differ. Confirm the specific suffix 'IZ' denotes the extended temperature grade compared to standard commercial versions. Check for obsolescence notices or PCNs regarding label changes before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this part when a 50kOhm resistance value is required with non-volatile retention. Ensure the system voltage aligns with the 4.5V-5.5V specification. Compare against X9317WV8IZT1 if a 10kOhm value is needed instead, or X9317ZV8IT1 for a 1kOhm option within the same package family.

Digital Potentiometers Part Context

This component belongs to the X9317 family of Digitally Controlled Potentiometers (XDCP). It shares architectural similarities with other members like X9317WV8IZT1 and X9317ZV8IT1, differing primarily in resistance value and temperature rating suffixes. The manufacturer is Renesas Electronics Corporation, formerly Intersil.

Digital Potentiometers Replacement Considerations

The X9317UV8IZ is listed as a parameter-equivalent alternative, typically available in tube packaging rather than tape and reel.
