CAT5114ZI-10GTMP

Digital Potentiometers Overview

The CAT5114ZI-10GTMP is a single-channel digital potentiometer manufactured by onsemi. It features a 10 kΩ resistance value with a linear taper and 32 adjustable taps. The device utilizes non-volatile EEPROM to store wiper positions, ensuring data retention without power. It operates on a single supply voltage ranging from 2.5 V to 6.0 V with a typical standby current of 100 µA. Control is managed via a 3-wire serial interface supporting up/down commands. The component is housed in an MSOP-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper settings after power loss
• 3-wire serial interface for simple digital control
• Low power consumption with 100 µA standby current
• Single supply operation from 2.5 V to 6.0 V

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 exact suffix 'ZIMP' against official onsemi documentation to confirm specific tape-and-reel or moisture sensitivity classifications. Confirm availability status as distribution channels may list obsolete or end-of-life variants under similar part numbers. Ensure the ordering information matches the required package type and environmental compliance standards.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer with 32 taps is required for linear resistance adjustment. The 10 kΩ value suits moderate impedance applications. Verify that the 3-wire serial interface is compatible with the host microcontroller's available pins. Ensure the operating voltage range of 2.5 V to 6.0 V aligns with the system power supply.

Digital Potentiometers Part Context

This part belongs to the CAT5114 family of 32-tap digital potentiometers. Variants in this series differ primarily by resistance values (10 kΩ, 50 kΩ, 100 kΩ) and package types (MSOP, TSSOP, PDIP). The ZI suffix typically denotes the MSOP-8 package, while the GTMP suffix indicates specific packaging and handling attributes defined by the manufacturer.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with identical electrical specifications but different packages, such as CAT5114TI-10-GT3 (TSSOP-8) or CAT5114LI-10-G (PDIP-8). Cross-family substitutes like the CAT5111 offer higher tap counts but require interface verification.
