X9313WPI

Digital Potentiometers Overview

The X9313WPI is a single-channel digital potentiometer IC from the X9313 series, manufactured by Renesas Electronics Corporation. It features a total resistance of 10 kOhms with a linear taper and 32 tap positions for precise adjustment. The device utilizes non-volatile memory to retain wiper settings upon power loss. It operates on a 5V supply voltage with a maximum current consumption of 1 mA. The component is housed in an 8-pin PDIP package and supports a serial interface for control.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 10 kOhm resistance and 32 taps
• Non-volatile EEPROM storage retains wiper position after power cycle
• Serial (3-Wire) interface for data input and control
• Linear taper characteristic with ±20% tolerance

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• Calibration of sensor outputs

Digital Potentiometers Procurement Notes

Verify the specific suffix 'P' indicates the PDIP package variant when sourcing. Confirm RoHS compliance status as some legacy listings may indicate non-compliance. Check for obsolescence notices as this part number has been marked as obsolete in certain distributor databases. Ensure the supplier provides valid traceability documentation for industrial applications.

Digital Potentiometers Selection Notes

Select this model for applications requiring through-hole mounting due to the PDIP package. Compare against SOIC-8 variants if surface mount space is limited. Ensure the system voltage does not exceed the 5.5V maximum rating. Verify that the 10 kOhm resistance value aligns with the circuit's impedance requirements compared to other available values like 1 kOhm or 50 kOhm.

Digital Potentiometers Part Context

This component belongs to the XDCP family of digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in environments where vibration resistance and long-term reliability are critical. The non-volatile feature distinguishes it from volatile counterparts that reset to default states upon power-up.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements include other X9313 series variants such as X9313WP (if PDIP is required) or X9313WSI (for SOIC packages). Cross-reference with Intersil branded parts as Renesas acquired Intersil. Verify that substitute parts maintain the same non-volatile memory architecture and serial interface protocol.
