CAT5113P-00

Digital Potentiometers Overview

The CAT5113P-00 is a single digital potentiometer IC from onsemi, designed as an electronic replacement for mechanical potentiometers. It features a 100-tap linear taper resistor array with non-volatile EEPROM wiper storage to retain settings during power loss. The device operates on a single supply voltage ranging from 2.5 V to 6.0 V and draws ultra-low standby current of 10 nA. It utilizes a serial up/down interface controlled by three input pins. Available in PDIP-8 packages, it supports resistance values including 10 kOhms and 50 kOhms, operating within a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM memory retains wiper position data without external power

• Tamper-proof calibration systems requiring persistent settings

Digital Potentiometers Procurement Notes

Verify the specific suffix designation against official datasheets to confirm resistance value and package type. Confirm RoHS compliance status and lead-free manufacturing details with the manufacturer. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure ordering specifications match the required industrial temperature range and interface compatibility.

Digital Potentiometers Selection Notes

Select this component when non-volatile memory retention is critical for maintaining calibrated settings across power cycles. The low standby current makes it suitable for battery-powered or energy-sensitive applications. Verify that the serial interface timing requirements align with the host controller's capabilities. Consider the physical package constraints and thermal performance for the intended PCB layout.

Digital Potentiometers Part Context

This part belongs to the CAT5113 series of digitally programmable potentiometers manufactured by onsemi. The series offers various resistance values and package options to replace mechanical pots in modern electronics. The P-00 suffix typically indicates a specific resistance value and package configuration within this family, designed for general-purpose analog control applications.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5113 variants with matching pinouts and electrical characteristics. Verify that substitute parts maintain the same non-volatile memory functionality and serial interface protocol. Ensure equivalent resistance tolerance and temperature coefficient specifications are met for critical calibration applications.
