X9313UMIZ-3

Digital Potentiometers Overview

The X9313UMIZ-3 is a single-channel, solid-state digital potentiometer manufactured by Renesas Electronics Corporation. It features 32 tap positions with a linear resistance taper and an end-to-end resistance of 50 kΩ. The device operates within a supply voltage range of 3 V to 5.5 V and utilizes a 3-wire serial interface for control. Key electrical parameters include a typical wiper resistance of 40 Ω, a maximum active current of 3 mA, and a standby current of 500 µA. The component incorporates nonvolatile memory to retain the wiper position upon power-up.

Digital Potentiometers Feature Summary

• Nonvolatile storage retains wiper position after power loss
• 3-wire serial interface (CS, U/D, INC) for control
• Linear resistance taper with 32 discrete taps
• Single channel configuration in MSOP-8 package

Digital Potentiometers Applications

• Digitally controlled resistance trimming
• Parameter adjustment in electronic circuits
• Signal processing applications requiring variable resistance

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range specifications compared to commercial variants. Confirm RoHS compliance status as some legacy listings indicate non-compliance. Check for direct replacement availability from the manufacturer due to potential obsolescence of older packaging styles.

Digital Potentiometers Selection Notes

Select this component when a 50 kΩ linear digital potentiometer with nonvolatile memory is required. Ensure the system supports the 3-wire serial interface protocol. Verify that the 500 µA standby current meets low-power design constraints. Compare against the X9313WMIZ-3 if a 10 kΩ resistance value is needed instead.

Digital Potentiometers Part Context

This part belongs to the XDCP™ family of digitally controlled potentiometers. It shares architectural similarities with the X9313W series but differs in total resistance value. The UMIZ-3 designation specifies the MSOP-8 surface-mount package variant within the broader X9313 product line.

Digital Potentiometers Replacement Considerations

The X9313UMZ-3 is listed as a direct replacement option.
