X9313WST1

Digital Potentiometers Overview

The X9313WST1 is a single-channel digital potentiometer IC from the Renesas X9313 series, featuring a 10 kOhm resistance value with a linear taper. It provides 32 taps for precise adjustment and utilizes non-volatile memory to retain wiper settings without power. The device operates on a 5 V supply voltage with a maximum operating current of 1 mA. It communicates via a serial 3-wire interface and is housed in an SOIC-8 surface-mount package. The component supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile storage retains wiper position data after power loss
• Linear resistance taper for consistent adjustment characteristics
• Serial 3-wire interface for simplified control connections

Digital Potentiometers Applications

• Industrial process control systems requiring adjustable gain or reference voltages
• Consumer electronics calibration circuits
• Audio equipment volume or tone control interfaces

Digital Potentiometers Procurement Notes

Verify the specific suffix 'WS' against official Renesas documentation to confirm the exact temperature grade and packaging type. Ensure compatibility with the target PCB footprint for the SOIC-8 package. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with non-volatile memory is required. The 10 kOhm resistance and 32-tap resolution suit applications needing moderate precision. Verify that the 3-wire serial interface aligns with the system's available microcontroller pins and that the SOIC-8 package fits the design constraints.

Digital Potentiometers Part Context

This part belongs to the X9313 family of CMOS EEPROM-based digital potentiometers. These devices are designed as solid-state replacements for mechanical potentiometers, offering improved reliability and programmability. The series typically includes variants with different resistance values and package options to support diverse electronic design requirements.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9313 series variants such as X9313WSIZT1 or X9313WSZT1, which share similar electrical characteristics but may differ in temperature rating or packaging.
