X9511WPZ

Overview

The X9511WPZ is a nonvolatile digital potentiometer from Renesas Electronics, part of the XDCP series. It features a 10 kΩ end-to-end resistance with linear taper and 32 wiper positions. The device uses a button interface for control and includes nonvolatile memory to retain settings. It operates on a single 5V supply and is housed in an 8-pin PDIP package. Key electrical parameters include a typical wiper resistance of 40 Ω and a temperature coefficient of 300 ppm/°C.

Feature Summary

• Nonvolatile memory retains wiper position after power loss
• 32-position resolution with 10 kΩ linear resistance
• Simple button interface for easy integration
• Single 5V supply operation

Applications

• Volume control in audio circuits
• Programmable gain adjustment for amplifiers
• Offset voltage trimming in signal conditioning
• Reference voltage setting for comparators

Procurement Notes

Verify component status as the X9511 series may be discontinued or subject to last-time buy notices. Confirm package type (PDIP vs SOIC) matches design requirements. Check RoHS compliance status for current production batches. Validate supplier authenticity due to potential obsolescence issues.

Selection Notes

Select X9511WPZ for applications requiring simple manual adjustment without complex serial interfaces. Ensure 32-step resolution meets precision needs. Consider thermal performance within specified operating range. Verify mechanical fit for through-hole mounting in final assembly.

Part Context

Part of Renesas' X9511 family of digitally controlled potentiometers. Designed for cost-sensitive applications needing nonvolatile adjustment capabilities. Alternative packages include X9511WSZ (SOIC). Family shares similar electrical characteristics but differs in packaging and pin configuration.

Replacement Considerations

Direct replacements may be limited due to discontinuation status. Evaluate X9511WSZ for surface-mount alternatives. Consider generic digital potentiometers with SPI/I2C interfaces if interface flexibility is acceptable. Verify pin compatibility before substitution.
