X9511WPIZ

Overview

The X9511WPIZ is a non-volatile digital potentiometer from the XDCP 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 adjustment and employs linear taper characteristics. It operates on a single 5V supply voltage and includes non-volatile memory to retain wiper settings upon power loss. The component is housed in an 8-pin PDIP package.

Feature Summary

• Non-volatile memory retains wiper position after power cycle
• Push-button interface for direct control without microprocessor
• 32 tap positions with 10 kΩ resistance and linear taper
• Operates on single 5V supply

Applications

• Volume control in audio equipment
• Gain adjustment in instrumentation circuits
• Voltage reference setting in power supplies
• Calibration adjustments in industrial sensors

Procurement Notes

Verify the specific suffix 'IZ' against official Renesas documentation to confirm lead-free status and RoHS compliance, as datasheets may list variants like WPI or WSIZ. Confirm availability status, as some X9511 variants are marked as obsolete or discontinued in distributor databases. Ensure the 8-pin PDIP package matches the target PCB footprint requirements.

Selection Notes

Select this component when a simple, processor-less volume or gain control is required. The push-button interface eliminates the need for SPI or I2C communication lines. Choose the 10 kΩ value if it matches the circuit impedance requirements. Verify that the 32-step resolution is sufficient for the application's precision needs compared to higher-resolution alternatives.

Part Context

The X9511 belongs to the XDCP (Digital Control Potentiometer) family, which integrates non-volatile memory with digital potentiometer functions. This series allows for manual adjustment via buttons while maintaining settings across power cycles. The X9511 specifically offers a basic interface suitable for cost-sensitive applications where complex digital interfaces are unnecessary.

Replacement Considerations

Check for pin-compatible alternatives within the X9511 series, such as X9511WP or X9511WSIZ, noting differences in packaging (PDIP vs SOIC) and compliance status. Verify if newer generations from Renesas offer improved specifications or availability, ensuring electrical parameters like resistance tolerance and temperature coefficient remain compatible.
