X9313ZPIZ

Digital Potentiometers Overview

The Intersil X9313ZPIZ is a single-channel, nonvolatile digital potentiometer featuring a 1 kΩ end-to-end resistance. It provides 32 wiper tap points controlled via a 3-wire serial interface (CS, U/D, INC). The device operates on a single supply voltage ranging from 3 V to 5.5 V, with active current consumption of 3 mA maximum and standby current of 500 µA maximum. The wiper position is stored in EEPROM and recalled upon power-up. It utilizes a linear taper and is housed in an 8-lead PDIP package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position for 100 years with 100,000 endurance cycles per bit
• 3-wire serial interface allows simple microcontroller control
• Terminal voltages range from -VCC to +VCC
• Linear resistance taper with ±20% tolerance

Digital Potentiometers Applications

• Digitally controlled resistance trimming in instrumentation
• Volume or gain adjustment in audio circuits
• Calibration systems requiring persistent setting storage

Digital Potentiometers Procurement Notes

Verify the specific suffix 'ZPIZ' against manufacturer documentation to confirm lead-free status and package type. Ensure compatibility with existing PCB footprints for the 8-lead PDIP configuration. Check for moisture sensitivity levels if reflow soldering is required.

Digital Potentiometers Selection Notes

Select this component when a low-resistance value (1 kΩ) is required for digital adjustment. The 32-tap resolution may be insufficient for high-precision applications; consider higher-tap variants if finer granularity is needed. Confirm that the 3-wire interface matches the available GPIO pins on the controlling processor.

Digital Potentiometers Part Context

The X9313 series belongs to Intersil's family of solid-state digital potentiometers. The 'Z' suffix typically denotes the 1 kΩ resistance value, while 'P' indicates the PDIP package and 'IZ' often signifies RoHS compliance. This part replaces older electromechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9313 variants with different resistance values (e.g., X9313W for 10 kΩ, X9313U for 50 kΩ) if the resistance requirement can change. Ensure any substitute maintains the 3-wire interface and nonvolatile memory feature.
