CAT5114ZD7I00GT3

Digital Potentiometers Overview

The CAT5114ZD7I00GT3 is a single digital potentiometer IC from onsemi, featuring 32 tap positions with linear taper. It operates on a single supply voltage ranging from 2.5 V to 6.0 V and includes non-volatile EEPROM storage for wiper settings. The device utilizes an Increment/Up-Down serial interface controlled by CS, U/D, and INC pins. With a resistance value of 100 kΩ, it serves as an electronic replacement for mechanical potentiometers in applications requiring automated or remote adjustments.

Digital Potentiometers Procurement Notes

Verify the exact package suffix and resistance code in the ordering information table to ensure compatibility with the specific application requirements. Confirm lead finish and shipping packaging details directly with the manufacturer or authorized distributors, as these may vary based on production lot and region.

Digital Potentiometers Selection Notes

Select the CAT5114 variant based on the required resistance value (10 kΩ, 50 kΩ, or 100 kΩ) and the preferred package type (PDIP, SOIC, TSSOP, MSOP, or TDFN). Ensure the operating voltage range of 2.5 V to 6.0 V matches the system power supply. Consider the industrial temperature range (-40°C to +85°C) for environmental suitability.

Digital Potentiometers Part Context

The CAT5114 series is designed to replace mechanical potentiometers and trim pots in high-volume production lines. It allows for programmable adjustments in environments where manual access is difficult or hazardous. The non-volatile memory retains the last stored wiper position after power cycles, ensuring consistent system behavior upon restart.

Digital Potentiometers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When replacing, verify pinout compatibility, especially regarding the interchangeability of RH and RL terminals. Ensure the new component meets the same electrical specifications, including resistance tolerance and operating voltage range.
