X9317UV8IZ

Digital Potentiometers Overview

The X9317UV8IZ is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features a 50 kOhm resistance value with 100 taps and linear taper characteristics. The device utilizes non-volatile memory to retain wiper settings and operates on a serial three-wire interface (U/D, INC, CS). It supports a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 50 uA. Designed for surface-mount applications, it is housed in an 8-TSSOP package and functions within a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power loss
• Linear taper with 100 discrete taps for precise resistance adjustment
• Low power consumption with 50 uA operating current
• Serial 3-wire interface for simplified control

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Programmable biasing networks

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IZ' confirms RoHS compliance and lead-free status as per manufacturer specifications. Confirm the package type is TSSOP-8 and check for any recent Product Change Notices (PCN) regarding labeling or fabrication site updates before finalizing procurement orders.

Digital Potentiometers Selection Notes

Select this component when a single digital potentiometer with non-volatile storage is required. Ensure the system operates within the 4.5 V to 5.5 V supply range. For lower voltage applications (2.7 V), consider the X9317UV8IZ-2.7 variant instead.

Digital Potentiometers Part Context

This part belongs to the X9317 family of CMOS digital potentiometers. It shares core electrical specifications with variants like X9317US8IZ but differs in packaging (TSSOP vs SOIC) and voltage rating. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct functional substitutes include X9317UV8IZ-2.7 for extended voltage range compatibility. Verify pinout and interface compatibility when considering cross-model replacements within the same family.
