X9313WS-3

Digital Potentiometers Overview

The Renesas X9313WS-3 is a digitally controlled potentiometer (XDCP) featuring a single resistive element with 32 wiper tap points and linear taper. It operates within a supply voltage range of 3V to 5.5V, supporting terminal voltages from -VCC to +VCC. The device utilizes a 3-wire serial interface for control and includes nonvolatile memory to retain the wiper position upon power-up. Key electrical parameters include an end-to-end resistance tolerance of ±20%, a temperature coefficient of 300 ppm/°C, and a maximum active current of 3mA. It is housed in an 8-lead SOIC package.

Digital Potentiometers Procurement Notes

Verify the specific suffix '-3' against official Renesas documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance level distinct from the standard tube-packaged X9313WS. Ensure the source component matches the required operating temperature range and package type before procurement.

Digital Potentiometers Selection Notes

Select this component when a solid-state replacement for mechanical potentiometers is required in space-constrained designs. The X9313WS-3 is suitable for applications needing precise resistance adjustment via digital signals without manual intervention. Consider the ±20% resistance tolerance and 300 ppm/°C temperature coefficient during circuit design to ensure accuracy requirements are met.

Digital Potentiometers Part Context

The X9313 belongs to the X9313 family of Digitally Controlled Potentiometers originally developed by Intersil and now manufactured by Renesas Electronics. This series provides a CMOS solution for replacing traditional mechanical pots in various industrial and consumer electronic applications.

Digital Potentiometers Replacement Considerations

Direct pin-compatible alternatives within the same family include the X9313WMZ (MSOP package) and X9313UMZ (50kΩ variant). Verify that substitute parts match the required resistance value (10kΩ for WS) and package footprint.
