X9313WSIT2

Digital Potentiometers Overview

The X9313WSIT2 is a Digitally Controlled Potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a linear resistance taper with 32 wiper tap points and a 3-wire serial interface for position control. The device incorporates nonvolatile memory to retain the wiper setting upon power-up. It operates on a single supply voltage of 3V or 5V, drawing a maximum active current of 3mA and a standby current of 500µA. The total end-to-end resistance is available in values such as 1kΩ, 10kΩ, and 50kΩ with a tolerance of ±20%. The component is housed in an 8-lead SOIC package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position data for 100 years with endurance of 100,000 data changes per bit.
• Linear taper with 32 resistive elements and terminal voltages ranging from -VCC to +VCC.
• Low power CMOS technology supporting 3V and 5V operation with minimal active and standby currents.

Digital Potentiometers Applications

• Volume control in audio equipment
• Programmable gain amplifiers
• Voltage reference adjustment
• System calibration

Digital Potentiometers Part Context

The X9313 belongs to the XDCP™ family of digitally controlled potentiometers. This series provides solid-state alternatives to mechanical potentiometers, offering durability and programmability. The 'WS' suffix typically denotes the 8-lead SOIC package variant within this product line.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available documentation. Designers should verify pin compatibility and electrical specifications when considering alternative digital potentiometer ICs.
