X9315WSZT1

Digital Potentiometers Overview

The X9315WSZT1 is a non-volatile digital potentiometer manufactured by Renesas Electronics Corporation. It features a single circuit with 32 taps and a total resistance of 10 kOhms. The device utilizes an Increment/Decrement (U/D, INC, CS) serial interface for control. It operates on a 5V supply voltage with a typical operating current of 50 uA. The component is housed in an 8-SOIC surface-mount package and offers a linear taper. Key electrical parameters include a contact resistance of 200 Ohms and a temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• 32-tap resolution with 10 kOhm total resistance
• Low power consumption with 50 uA operating current
• Linear taper configuration for precise adjustment

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal processing circuits
• Voltage reference setting in measurement systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as it varies by manufacturing date and region. Check for obsolescence notices from Renesas, as older variants may be discontinued. Ensure the 8-SOIC footprint matches the PCB design constraints.

Digital Potentiometers Selection Notes

Select this model for applications requiring non-volatile storage of resistance settings without external memory components. Compare against X9315WSIZ if tube packaging is preferred over reels. Consider the X9315WMZ series if a smaller MSOP-8 package is required instead of SOIC-8.

Digital Potentiometers Part Context

This part belongs to the XDCP™ family of digital potentiometers from Renesas. It is functionally similar to other X9315 variants but distinguished by its specific packaging and commercial temperature range specifications. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

X9315WSIZ is a direct substitute available in tube packaging. X9315WSZ is another compatible variant in tube form. Verify pinout compatibility before replacing with any alternative digital potentiometer.
