X9314WSZT1

Digital Potentiometers Overview

The X9314WSZT1 is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features a 10 kΩ end-to-end resistance with a logarithmic taper and 32 tap points. The device utilizes a nonvolatile memory architecture to retain wiper position settings during power-off, recalling the last state upon power-up. It operates on a supply voltage range of 3.0 V to 5.5 V and communicates via a three-wire serial interface consisting of Chip Select (CS), Up/Down (U/D), and Increment (INC) inputs. The component is housed in an 8-lead SOIC package.

Digital Potentiometers Feature Summary

• Nonvolatile storage of wiper position for data retention without power
• Logarithmic resistance taper with 32 discrete tap points
• Three-wire serial interface (CS, U/D, INC) for digital control
• Operates within a 3.0 V to 5.5 V supply voltage range

Digital Potentiometers Applications

• Digitally controlled resistance trimming in audio equipment
• Parameter adjustment in signal processing circuits
• Volume control applications requiring logarithmic response
• Calibration systems needing persistent setting storage

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as older variants may differ. Check for obsolescence notices from Renesas, as this model series has historical discontinuation patterns. Ensure the logarithmic taper specification matches the application requirements compared to linear alternatives.

Digital Potentiometers Selection Notes

Select this component for applications requiring persistent analog resistance settings controlled digitally. The logarithmic taper is suitable for audio volume controls where human perception of loudness is logarithmic. Verify that the 10 kΩ resistance value fits the circuit impedance constraints. Ensure the operating temperature range meets the system environment specifications.

Digital Potentiometers Part Context

The X9314 belongs to the XDCP™ family of solid-state potentiometers. It serves as a digital alternative to mechanical potentiometers, offering higher reliability and longer life cycles. The 'WSZ' designation typically refers to the SOIC-8 package and commercial temperature grade, while 'T1' denotes reel packaging. This component integrates EEPROM technology to store the wiper position.

Digital Potentiometers Replacement Considerations

Direct substitutes include the X9314WSZ-3 for tube packaging or other X9314 variants with compatible pinouts. For linear taper requirements, consider the X9313 or X9315 series. Verify that replacement parts maintain the same 32-tap resolution and nonvolatile memory functionality.
