X9313UM-3T2

Digital Potentiometers Overview

The X9313UM-3T2 is a single-channel digital potentiometer IC manufactured by Renesas Electronics Corporation. It features a total resistance of 50 kOhms and provides 32 discrete taps for precise adjustment. The device utilizes non-volatile EEPROM memory to retain wiper settings upon power loss. It operates with an up/down interface (U/D, INC, CS) and supports a supply voltage range of 3V to 5.5V. The component is housed in an 8-MSOP package and is designed for surface-mount installation.

Digital Potentiometers Feature Summary

• Incorporates non-volatile EEPROM memory to maintain resistance settings without external power
• Utilizes a simple three-wire serial interface for control and data transfer
• Provides linear taper characteristics for consistent resistance adjustment

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of direct substitutes such as the X9313UMZ series if production continuity is required. Ensure that the replacement component matches the original pinout and electrical specifications to avoid redesign efforts. Check RoHS compliance status as the original may not meet current environmental standards.

Digital Potentiometers Selection Notes

Select this component when a compact, non-volatile digital potentiometer is required for low-power applications. The 50k Ohm resistance value suits moderate impedance circuits. The 32-tap resolution offers sufficient granularity for many analog control tasks. Consider the ±20% tolerance and temperature coefficient when designing for high-precision environments.

Digital Potentiometers Part Context

This component belongs to the XDCP™ series of digital potentiometers from Renesas. It is part of a family of solid-state variable resistors designed to replace mechanical potentiometers. The series typically includes various resistance values and tap counts to suit different application requirements.
