X9313WM-3

Digital Potentiometers Overview

The X9313WM-3 is a digitally controlled potentiometer (digital pot) manufactured by Renesas Electronics Corporation. It features a single resistive element with a total resistance of 10 kOhms and 32 tap positions for precise adjustment. The device utilizes a non-volatile memory architecture to retain the wiper setting upon power loss, ensuring data integrity without continuous power supply. It operates on a 5V supply voltage and communicates via a 3-wire serial interface compatible with standard SPI protocols. The component is housed in an 8-pin MSOP surface-mount package and is designed for industrial temperature ranges.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 3-wire serial interface (U/D, INC, CS) for control
• Linear taper with 32 discrete tap positions
• Single channel configuration with 10 kOhm resistance

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Sensor calibration systems

Digital Potentiometers Part Context

The X9313WM-3 belongs to the XDCP series of digital potentiometers from Renesas. This series is characterized by its CMOS technology and EEPROM-based storage. The 'WM' suffix typically denotes the MSOP-8 package variant, while the '-3' often indicates specific tape and reel packaging or minor manufacturing revisions within the same functional specification.

Digital Potentiometers Replacement Considerations

The X9313WMZ is listed as a direct replacement for the X9313WM. When substituting, verify that the RoHS compliance status matches project requirements, as the original X9313WM may not be RoHS compliant depending on the specific manufacturing batch date.
