X9314WSZ

Digital Potentiometers Overview

The X9314WSZ is a single-channel digitally controlled potentiometer (XDCP) from Renesas Electronics, part of the XDCP series. It features a 10 kΩ end-to-end resistance with a logarithmic taper and 32 taps. The device utilizes a nonvolatile memory to store wiper positions, allowing recall upon power-up. It operates on a supply voltage range of 3 V to 5.5 V and communicates via a three-wire serial interface (U/D, INC, CS). Packaged in an 8-SOIC surface-mount case, it is designed for applications requiring precise digital resistance adjustment.

Digital Potentiometers Feature Summary

• Nonvolatile storage retains wiper position after power loss
• Logarithmic taper with 32 discrete tap points
• Three-wire serial interface for control
• Operates within 3 V to 5.5 V supply range

Digital Potentiometers Applications

• Digitally controlled resistance trimming
• Parameter adjustments in audio or signal processing circuits
• Calibration systems requiring persistent settings

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as historical data indicates variations between leaded and lead-free versions. Confirm package dimensions match the 8-SOIC specification (0.154 inch width). Ensure the specific suffix 'Z' denotes lead-free construction if required by assembly standards. Check current manufacturing status as older variants may be obsolete.

Digital Potentiometers Selection Notes

Select this component when a logarithmic response curve is necessary for volume control or similar applications. The 10 kΩ resistance value suits moderate impedance circuits. Verify that the 32-tap resolution meets the required adjustment precision. Ensure the operating temperature range of 0°C to 70°C aligns with the system environment.

Digital Potentiometers Part Context

This component belongs to the X9314 family of solid-state potentiometers. It serves as a direct replacement for legacy Intersil parts with compatible pinouts and electrical characteristics. The 'WSZ' suffix typically indicates a lead-free, RoHS-compliant version in the SOIC-8 package, distinguishing it from older leaded variants like the X9314WS-3.

Digital Potentiometers Replacement Considerations

The X9314WSZ-3T1 is listed as a direct substitute. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
