X9313UP

Digital Potentiometers Overview

The X9313UP is a digitally controlled potentiometer (XDCP) manufactured by Intersil. It features a linear resistance taper with 32 wiper tap points and a total of 31 resistive elements. The device utilizes a 3-wire serial interface to control the wiper position, which is stored in nonvolatile memory for recall upon power-up. It operates on low-power CMOS technology with supply voltages of 3V or 5V. The end-to-end resistance tolerance is ±20%, and terminal voltages range from -VCC to +VCC.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position data for 100 years with endurance of 100,000 data changes per bit.
• 3-wire serial interface controls 32 wiper tap points on a linear taper resistor array.
• Low power consumption with active current max 3mA and standby current max 500µA at VCC = 3V or 5V.

Digital Potentiometers Applications

• Solid-state potentiometer replacement in industrial control systems.
• Gain adjustment in audio and signal processing circuits.
• Voltage reference trimming in measurement equipment.

Digital Potentiometers Part Context

The X9313UP belongs to the X9313 series of digital potentiometers. This family includes variants with different resistance values such as 1kΩ, 10kΩ, and 50kΩ. The 'UP' suffix typically denotes an 8-lead PDIP package, distinguishing it from SOIC or MSOP package options available in the same series.

Digital Potentiometers Replacement Considerations

Substitutes must match the 32-tap count, linear taper, and 3-wire interface. Verify that the alternative component supports the required voltage range (-VCC to +VCC) and offers comparable nonvolatile memory retention specifications.
