X9511WST2

Overview

The X9511WST2 is a single-channel, nonvolatile digital potentiometer from the XDCP series by Renesas Electronics. It features a 10 kΩ resistance value with 32 linear tap points and is controlled via push-button inputs (PU/PD). The device stores wiper positions in EEPROM for recall upon power-up. It operates on a single 5V supply, supports terminal voltages up to ±5V, and is housed in an 8-lead SOIC package. Key electrical parameters include a typical standby current of 100µA, active current max 3mA, and a temperature coefficient of 300 ppm/°C.

Feature Summary

• Push-button controlled interface with slow and fast scan modes
• Nonvolatile memory retains wiper position for 100 years
• Single channel with 32 taps and 10 kΩ end-to-end resistance
• Operates within -40°C to +85°C industrial temperature range

Applications

• Resistance trimming in push-button controlled circuits
• Volume or gain control in audio equipment
• Calibration settings in industrial instrumentation

Procurement Notes

Verify component status as the X9511 family has been subject to End-of-Life notices. Confirm availability through authorized distributors or secondary market suppliers. Check for RoHS compliance and specific suffix variations such as 'T2' which may indicate tape-and-reel packaging. Ensure datasheet revisions match design requirements.

Selection Notes

Select this component when manual adjustment via push buttons is required without microcontroller interfaces. Compare against SPI/I2C digital potentiometers if space or pin count is constrained. Verify that the 10 kΩ resistance and ±5V terminal voltage range align with the application's signal levels. Consider the 32-tap resolution for required precision.

Part Context

The X9511 belongs to the XDCP (Digital Potentiometer) family, originally developed by Intersil and acquired by Renesas. It is designed for applications requiring persistent resistance settings without continuous power. The SOIC-8 package offers a compact surface-mount solution compared to the PDIP variant.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Users should consult Renesas for current equivalent recommendations or verify compatibility with generic push-button digital potentiometers having similar pinouts and electrical specs.
