X9511WSIZ

Overview

The X9511WSIZ is a single-channel nonvolatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a 10 kΩ end-to-end resistance with a linear taper and 32 discrete tap positions. The device utilizes a push-button interface for wiper control and includes nonvolatile memory to retain settings during power loss. It operates on a single 5 V supply within an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC surface-mount format, it offers a typical wiper resistance of 40 Ω and a temperature coefficient of 300 ppm/°C.

Feature Summary

• Nonvolatile storage retains wiper position across power cycles
• Push-button interface for direct hardware control
• Single channel with 10 kΩ resistance and 32 taps
• Industrial operating temperature range (-40°C to +85°C)

Applications

• Volume control in audio circuits
• Programmable gain adjustment for voltage amplifiers
• Offset voltage trimming in amplifier circuits

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's current datasheet to confirm RoHS compliance status and exact package dimensions. Confirm that the push-button interface meets system requirements, as this model lacks serial communication capabilities found in other variants.

Selection Notes

Select the X9511WSIZ when nonvolatile memory retention is required without serial bus complexity. Ensure the 10 kΩ resistance value aligns with circuit impedance needs. Verify that the 32-tap resolution is sufficient for the intended application compared to higher-resolution alternatives.

Part Context

This component belongs to the X9511 family of digitally controlled potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance adjustments. The series integrates resistive arrays with electronic switches controlled by internal logic.

Replacement Considerations

The X9511WSIT1 is listed as a discontinued direct substitute. Verify pinout compatibility and electrical specifications before replacing the X9511WSIZ with alternative digital potentiometer models.
