CAT5114LI-00-G

Digital Potentiometers Overview

The CAT5114LI-00-G is a single digital potentiometer IC from onsemi, featuring a 100 kΩ linear taper resistor array with 32 tap positions. It operates on a single supply voltage ranging from 2.5 V to 6.0 V and draws a standby current of typically 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

• Non-volatile EEPROM storage retains wiper position after power down
• Increment/Up-Down serial control interface for easy integration
• Single supply operation between 2.5 V and 6.0 V
• Industrial temperature range from -40°C to +85°C

Digital Potentiometers Applications

• Automated product calibration
• Remote control adjustments
• Offset, gain, and zero control circuits
• Tamper-proof calibration systems

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'L' corresponds to the PDIP-8 package and 'I' indicates the industrial temperature grade. Confirm that the '00' suffix denotes the 100 kΩ resistance value. Check current availability status as manufacturing lifecycles may change. Ensure compliance with RoHS and lead-free requirements if applicable to the assembly process.

Digital Potentiometers Selection Notes

Select this part when a non-volatile digital potentiometer with up/down control is required. The 100 kΩ resistance value suits applications needing higher impedance levels. The PDIP-8 package is suitable for through-hole mounting. Verify that the 32-tap resolution meets the system's adjustment precision needs compared to other available tap counts.

Digital Potentiometers Part Context

This component belongs to the CAT5114 series of 32-tap digital potentiometers. The 'LI-00-G' designation specifies the PDIP-8 package, industrial temperature rating, 100 kΩ resistance, and green/RoHS compliant packaging. Other variants exist with different resistances, packages, and interfaces within the same family.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with matching resistance and interface. Cross-family substitutes like CAT5113 or CAT5115 require verification of interface compatibility (serial vs. up/down) and memory type (volatile vs. non-volatile). Package pinouts must be checked for direct socketing compatibility.
