X9314WSIZ

Digital Potentiometers Overview

The X9314WSIZ is a single digitally controlled potentiometer (XDCP) from Renesas Electronics, part of the XDCP series. It features a logarithmic resistance taper with an end-to-end resistance of 10 kΩ and 32 taps. The device utilizes a nonvolatile memory type to store wiper positions, ensuring data retention for up to 100 years. It operates on a supply voltage range of 3.0 V to 5.5 V and employs a three-wire serial interface (Up/Down, Increment, Chip Select). The component is housed in an 8-SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile storage and recall of wiper position upon power-up
• Logarithmic taper with 32 taps and 10 kΩ total resistance
• Three-wire serial interface (U/D, INC, CS)
• Standby current less than 500 µA at VCC = 3V

Digital Potentiometers Applications

• Digitally controlled resistance trimming
• Audio volume control applications
• Parameter adjustments in signal processing circuits

Digital Potentiometers Procurement Notes

Verify RoHS compliance status through official datasheets or manufacturer notices, as historical records indicate variations within the X9314 family. Confirm the specific suffix 'IZ' denotes industrial temperature range (-40°C to +85°C) and SOIC-8 packaging. Check for Product Change Notices (PCN) regarding label updates or manufacturing site changes before procurement.

Digital Potentiometers Selection Notes

Select this component when a logarithmic response curve is required for audio or sensor applications. Ensure the system interface supports the three-wire Up/Down protocol. Verify that the 10 kΩ resistance value fits the circuit's impedance requirements and that the 32-tap resolution meets the necessary adjustment precision. Compare against linear taper variants if logarithmic behavior is not needed.

Digital Potentiometers Part Context

The X9314WSIZ belongs to the Intersil/Renesas X9314 family of solid-state potentiometers. It serves as a digital alternative to mechanical potentiometers, offering higher reliability and nonvolatile memory capabilities. The 'W' indicates the SOIC package, 'I' specifies the industrial temperature range, and 'Z' typically denotes lead-free/RoHS compliant construction in Renesas nomenclature.

Digital Potentiometers Replacement Considerations

Direct replacement options include other X9314 variants with compatible packages and electrical specifications. Verify pinout compatibility and interface logic levels. For RoHS-compliant versions, ensure the substitute part carries the appropriate environmental certification suffix.
