X9511WSIT1

Overview

The X9511WSIT1 is a non-volatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a single circuit with 32 taps and a resistance value of 10 kΩ. The device utilizes a push-button interface for control and operates on a 5V supply voltage. Packaged in an 8-SOIC surface-mount format, it maintains its wiper position without power. Key electrical parameters include a typical temperature coefficient of 300 ppm/°C, a contact resistance of 40 Ω, and a tolerance of ±20%. The component supports an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile memory retains wiper settings after power loss
• Push-button interface for direct user control
• Single circuit configuration with 32 linear taps
• Operates at 5V with low standby current

Applications

• Audio volume control systems
• Calibration of sensor circuits
• Adjustable gain amplifiers
• User interface parameter adjustment

Procurement Notes

Verify RoHS compliance status as sources indicate conflicting data regarding environmental specifications. Confirm package type accuracy, as suffixes may denote tape-and-reel versus tube packaging. Check for obsolescence notices or product change notifications (PCN) prior to procurement, as this part number has been marked as obsolete in some distributor records.

Selection Notes

Select this component when a simple, hardware-controlled digital potentiometer is required without complex serial interfaces like I2C or SPI. Ensure the application requires a linear taper and can accommodate a 10kΩ resistance value. Verify that the system design allows for physical button inputs to drive the UP/DOWN pins directly.

Part Context

This part belongs to the X9511 family of non-volatile digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring manual adjustment but needing reliability and longevity. The 'WSIT1' suffix typically indicates specific packaging and environmental compliance variations within the broader X9511 product line.

Replacement Considerations

X9511WSIZT1 is listed as a direct substitute.
