X9511WP

Overview

The X9511WP is a non-volatile digital potentiometer 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 control interface for wiper adjustment and incorporates non-volatile memory to retain the setting upon power loss. It is housed in an 8-pin PDIP package, supporting surface or through-hole mounting depending on the specific variant suffix, with a typical operating voltage of 5V.

Feature Summary

• Non-volatile memory retains wiper position after power cycle
• Push-button interface for direct user control
• 32 discrete tap positions with linear taper
• 10 kΩ nominal resistance with ±20% tolerance

Applications

• Volume control in audio equipment
• User-adjustable gain settings in instrumentation
• Calibration adjustments in industrial sensors
• Lighting dimmer circuits

Procurement Notes

Verify the exact suffix (e.g., WP vs WPI) as it determines the package type (PDIP vs PLCC) and lead-free status. Check RoHS compliance status as some variants may be restricted. Confirm availability as older digital potentiometer lines may have limited stock or end-of-life status from primary distributors.

Selection Notes

Select based on required package style; WP typically denotes PDIP while other suffixes may indicate different footprints. Ensure the 10 kΩ resistance matches the circuit impedance requirements. Verify that the push-button interface aligns with the user input design constraints compared to SPI/I2C alternatives.

Part Context

Part of the X9511 series of non-volatile digital potentiometers. This family focuses on simple, robust control interfaces suitable for applications where microcontroller overhead for digital pots is undesirable. It serves as a drop-in replacement for mechanical potentiometers in many analog control loops.

Replacement Considerations

Direct pin-compatible replacements include other X9511 variants with different package suffixes (e.g., X9511WS for SOIC). Cross-brand equivalents require verification of interface compatibility and memory retention behavior.
