CAT5113LI-01-G

Digital Potentiometers Overview

The CAT5113LI-01-G is a single digital potentiometer IC from onsemi, featuring a 1 kΩ linear taper resistor array with 100 tap positions. It operates on a single supply voltage ranging from 2.5 V to 6.0 V and draws a maximum standby current of 1 µA. The device utilizes an increment/up-down serial interface controlled by CS, U/D, and INC pins. Its wiper position is stored in nonvolatile EEPROM memory, ensuring retention during power loss. The component is housed in an 8-pin PDIP package.

Digital Potentiometers Feature Summary

• 100-position linear taper potentiometer with 1 kΩ resistance
• Non-volatile EEPROM storage for wiper position retention
• Increment/Up-Down serial control interface (CS, U/D, INC)
• Single supply operation: 2.5 V to 6.0 V

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibrations
• Programmable analog functions

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'L' for PDIP packaging and '01' for 1 kΩ resistance against the manufacturer's official documentation. Confirm RoHS compliance status and lead finish specifications (NiPdAu) prior to procurement. Check for any active product change notifications or discontinuation notices directly from onsemi.

Digital Potentiometers Selection Notes

Select this component when a 1 kΩ linear digital potentiometer with nonvolatile memory is required. Ensure the application supports the 2.5 V to 6.0 V supply range and utilizes the three-wire serial interface. Consider the PDIP-8 package constraints for PCB layout and thermal management within the -40°C to +85°C industrial temperature range.

Digital Potentiometers Part Context

This part belongs to the CAT5113 family of 100-tap digital potentiometers. The 'L' suffix denotes the PDIP-8 through-hole package, while '01' specifies the 1 kΩ resistance value. Other variants in the series include different resistance values (10 kΩ, 50 kΩ, 100 kΩ) and surface-mount packages like SOIC, TSSOP, and MSOP.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include CAT5113VI-01-G (SOIC-8), CAT5113YI-01-G (TSSOP-8), and CAT5113ZI-01-G (MSOP-8). These share identical electrical characteristics but differ in physical package dimensions and mounting style.
