X9511WSZ

Overview

The X9511WSZ is a nonvolatile digital potentiometer from the X9511 series, manufactured by Renesas Electronics. It features a single potentiometer circuit with 32 taps and a resistance value of 10 kΩ. The device utilizes a push-button interface for control and employs linear taper characteristics. It operates on a single 5V supply voltage and is housed in an 8-pin SOIC package. Key electrical parameters include a temperature coefficient of 300 ppm/°C and a typical wiper resistance of 40 Ω.

Feature Summary

• Nonvolatile memory retains wiper position data without power
• Push-button interface for direct user control
• 32-tap resolution with linear taper
• Single 5V supply operation

Applications

• Volume control in audio circuits
• Gain adjustment in voltage amplifiers
• Programmable reference voltage generation
• Offset voltage trimming

Procurement Notes

Verify component status as the related X9511WSZT1 variant is marked as obsolete. Confirm availability through authorized distributors or secondary market suppliers. Check RoHS compliance status and ensure the specific suffix matches the required packaging format (tube vs. tape and reel) for production integration.

Selection Notes

Select this component when a simple, hardware-controlled digital potentiometer is required without serial communication overhead. Ensure the application supports the 10 kΩ resistance range and 5V logic levels. Consider the 32-step resolution limits for fine adjustments compared to higher-resolution SPI-based alternatives like the X9110.

Part Context

The X9511WSZ belongs to the XDCP™ family of digitally controlled potentiometers. It is part of the broader X9511 series which offers various interface options and resistance values. This specific model focuses on ease of use via push-button controls rather than complex digital bus interfaces.

Replacement Considerations

Direct replacements may be limited due to the obsolescence of similar variants. Evaluate other Renesas X9511 models with compatible packages or consider generic digital potentiometers with push-button interfaces if pin compatibility allows.
