X9511WSI

Overview

The X9511WSI is a non-volatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a single circuit with 32 tap positions 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-SOIC surface-mount package. Key electrical parameters include a typical contact resistance of 40 Ω, a tolerance of ±20%, and a temperature coefficient of 300 ppm/°C.

Feature Summary

• Non-volatile memory retains wiper position upon power loss
• Push-button interface for direct user control without microcontrollers
• 32 discrete tap positions with linear resistance taper
• Single-channel configuration in compact 8-SOIC package

Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• User-adjustable threshold settings

Procurement Notes

Verify component status as listings indicate potential obsolescence or discontinuation. Confirm RoHS compliance status, as some variants are marked non-compliant. Check for available direct replacements such as the X9511WSIZT1 if current stock is unavailable. Validate packaging type (tube vs. reel) against specific manufacturing requirements.

Selection Notes

Select this component when non-volatile storage is required to maintain setting after power cycles. Ensure the 10 kΩ resistance range fits the application's impedance constraints. Verify that the push-button interface meets system control needs without additional digital logic. Consider the ±20% tolerance and 300 ppm/°C temperature coefficient for precision requirements.

Part Context

The X9511WSI belongs to the X9511 family of non-volatile digital potentiometers. This series integrates EEPROM to store wiper positions, eliminating the need for external memory components. The WS suffix typically denotes the SOIC-8 package variant within the product line.

Replacement Considerations

X9511WSIZT1 is listed as a direct replacement option.
