X9313UST2

Digital Potentiometers Overview

The X9313UST2 is a single-channel solid-state digital potentiometer manufactured by Renesas Electronics Corporation. It features a total resistance of 50 kΩ with 32 wiper taps and linear taper characteristics. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a non-volatile memory architecture to retain the wiper position upon power loss. It communicates via a standard 3-wire serial interface (U/D, INC, CS) and is housed in an 8-pin SOIC package.

Digital Potentiometers Feature Summary

• Non-volatile storage retains wiper settings without power
• 3-wire serial interface for control
• Linear resistance taper with 32 taps
• Single channel configuration

Digital Potentiometers Applications

• Volume control in audio systems
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Programmable filter frequency setting

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T2' against official Renesas documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure compatibility with standard SOIC-8 footprint requirements during PCB layout design.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer with 50 kΩ resistance is required. Verify that the operating environment stays within the commercial temperature range of 0°C to +70°C. Confirm that the 3-wire interface aligns with the host microcontroller's available GPIO pins.

Digital Potentiometers Part Context

This part belongs to the XDCP™ series of digital potentiometers from Renesas. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance adjustments without moving parts.

Digital Potentiometers Replacement Considerations

Compatible pin-for-pin replacements include the X9313USZT1 and X9313USZ variants. Verify package dimensions and thermal characteristics before substitution.
