WMS7130010S

Digital Potentiometers Overview

The WMS7130010S is a single-channel, non-volatile digital potentiometer manufactured by Winbond (distributed by Nuvoton). It features 32 taps and an end-to-end resistance of 10 kΩ. The device operates on a single supply voltage ranging from 2.7V to 5.5V within an industrial temperature range of -40°C to +85°C. It utilizes a 3-wire Up/Down serial interface for control and includes one non-volatile memory location to automatically recall the wiper position upon power-up.

Digital Potentiometers Feature Summary

• Single linear-taper channel with 32 resolution taps
• Non-volatile memory retains wiper position across power cycles
• 3-wire Up/Down serial interface (CS, INC, U/D)
• Industrial temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference trimming
• RF amplifier control

Digital Potentiometers Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Winbond Electronics Corporation as the producer while the model is associated with Nuvoton Technology Corporation in external listings. Confirm the package type matches the 'S' suffix (SOIC) and ensure the component meets the specific industrial temperature requirements for the target environment.

Digital Potentiometers Selection Notes

Select the WMS7130010S when a 10 kΩ variable resistance is required without an output buffer. If an integrated output buffer is necessary for driving loads, the WMS7131 series should be selected instead. Ensure the application supports the 3-wire serial control logic and does not require more than 32 adjustment steps.

Digital Potentiometers Part Context

This component belongs to the WMS713x family of non-volatile digital potentiometers. The '0' in the part number indicates the absence of an output buffer, distinguishing it from the WMS7131 series which includes a buffer. The '010' suffix specifies the 10 kΩ resistance value, while 'S' denotes the SOIC package.

Digital Potentiometers Replacement Considerations

Direct replacements include other WMS7130 variants with different resistance values (WMS7130050S for 50 kΩ or WMS7130100S for 100 kΩ). For buffered applications, the WMS7131 series serves as the functional equivalent with added output drive capability.
