X9315WSIZ

Digital Potentiometers Overview

The X9315WSIZ is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single circuit with 32 taps and a total resistance of 10 kOhms. The device utilizes a nonvolatile memory architecture to retain wiper position settings during power-off events, allowing for recall upon subsequent power-up. It operates on a 5V supply voltage and employs a 3-wire serial interface consisting of U/D, INC, and CS inputs for control. The component is housed in an 8-SOIC surface-mount package and supports a linear taper configuration.

Digital Potentiometers Feature Summary

• Nonvolatile memory storage retains wiper position data without external power
• 3-wire serial interface (U/D, INC, CS) for digital control
• Single circuit with 32 adjustable taps and 10 kOhm resistance
• Linear taper characteristic with ±20% tolerance

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Sensor calibration offset adjustment

Digital Potentiometers Procurement Notes

Verify RoHS3 compliance status as the standard suffix indicates environmental compliance. Confirm package dimensions match the 8-SOIC specification (0.154 inch width). Ensure design accounts for the specific operating temperature range of -40°C to 85°C. Check for any recent PCN updates regarding labeling or manufacturing site changes before finalizing procurement.

Digital Potentiometers Selection Notes

Select this part when nonvolatile retention of analog settings is required without external battery backup. Compare against X9315WSI if lead-free processing is mandatory, as the 'Z' suffix denotes RoHS3 compliance. Verify that the 10 kOhm resistance value and 32-tap resolution meet the circuit's precision requirements. Ensure the 5V supply voltage aligns with the system's power rails.

Digital Potentiometers Part Context

The X9315WSIZ belongs to the X9315 family of low-noise, low-power digitized potentiometers originally developed by Intersil and now produced by Renesas. This series is designed to replace mechanical potentiometers in applications requiring digital adjustability and reliability. The 'Z' suffix specifically identifies the lead-free, RoHS-compliant version of the component.

Digital Potentiometers Replacement Considerations

The X9315WSI is a direct substitute but lacks RoHS3 compliance. For tape-and-reel packaging options, consider the X9315WSZT1 variant, noting its commercial temperature range (0°C to 70°C) differs from the industrial range of the WSIZ.
