X9511WSIT2

Overview

The X9511WSIT2 is a non-volatile digital potentiometer from the X9511 series manufactured by Renesas Electronics. It features a single potentiometer circuit with 32 tap positions and a resistance value of 10 kΩ. The device utilizes a push-button control interface for wiper adjustment and incorporates non-volatile memory to retain settings without power. It operates on a single 5V supply voltage and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• Push-button interface for direct user control
• 32 discrete tap positions with linear taper
• Single-channel 10 kΩ resistance configuration

Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• LED brightness dimming

Procurement Notes

Verify the specific suffix IT2 against official Renesas documentation to confirm tape-and-reel packaging details and ensure compatibility with automated assembly processes. Confirm RoHS compliance status as historical data indicates variations within the X9511 family.

Selection Notes

Select this component when a simple, low-pin-count solution for manual or mechanical adjustment is required. The push-button interface eliminates the need for complex digital buses like I2C or SPI. Ensure the 10 kΩ resistance and 32-step resolution meet the application's precision requirements.

Part Context

The X9511WSIT2 belongs to the XDCP™ (Digital Potentiometer) family. It serves as a solid-state replacement for traditional mechanical potentiometers in applications requiring durability and programmability without external microcontroller intervention for basic adjustments.

Replacement Considerations

Check for active alternatives such as the X9511WPI or X9511WPZ if different packaging (PDIP) is preferred. Verify pinout compatibility before substituting with other non-volatile digital potentiometers.
