X9511WS

Overview

The X9511WS is a nonvolatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a 10 kΩ end-to-end resistance with a linear taper and 32 discrete tap positions. The device utilizes a push-button interface for control and includes nonvolatile memory to retain wiper settings during power loss. Packaged in an 8-pin SOIC surface-mount format, it operates on a single 5V supply. 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 across power cycles
• Push-button control interface eliminates need for complex serial protocols
• 32-tap resolution with 10 kΩ linear resistance
• Single 5V supply operation

Applications

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

Procurement Notes

Verify component status as sources indicate the X9511WS may be discontinued or obsolete. Confirm RoHS compliance status, as some listings mark this specific variant as non-compliant. Validate package dimensions against the 8-SOIC specification (0.154 inch width) before integration into new designs.

Selection Notes

Select this component when nonvolatile storage is required without serial communication overhead. Ensure the application supports push-button input signals. Compare against the X9511WPI if through-hole packaging is preferred. Verify that the 32-step resolution meets the precision requirements of the target circuit.

Part Context

The X9511WS belongs to the X9511 family of digitally controlled potentiometers. It shares core architecture with variants like the X9511WPI but differs in packaging. The XDCP technology integrates resistive elements with switches controlled by a wiper counter register and data registers.

Replacement Considerations

The X9511WPI serves as a pin-compatible alternative in PDIP-8 packaging. Check datasheets for interface compatibility and electrical parameter matching before substitution.
