CAT5114Z-00

Digital Potentiometers Overview

The CAT5114Z-00 is a single-channel digital potentiometer from the onsemi CAT5114 series, designed as an electronic replacement for mechanical trimmers. It features a 32-tap linear taper resistor array with non-volatile EEPROM wiper storage, retaining settings during power loss. The device operates on a single supply voltage between 2.5 V and 6.0 V with low standby current. Control is managed via an Increment/Decrement interface using CS, U/D, and INC pins. This specific variant utilizes an MSOP-8 surface-mount package and supports operation within commercial temperature ranges.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm RoHS compliance and lead-free status against current manufacturing standards. Check for end-of-life notices or obsolescence warnings prior to procurement, as availability may be limited. Ensure packaging specifications match design requirements for MSOP-8 surface mount assembly.

Digital Potentiometers Selection Notes

Select this model for applications requiring non-volatile resistance adjustment without serial communication complexity. The 32-tap resolution suits moderate precision needs compared to higher-resolution counterparts. Verify that the 100 kΩ nominal resistance aligns with circuit impedance requirements. Ensure the MSOP-8 footprint fits the PCB layout constraints and thermal management strategy.

Digital Potentiometers Part Context

The CAT5114 series serves as a programmable alternative to mechanical potentiometers in high-volume production environments. It eliminates manual trimming by allowing digital adjustment of resistance values. The non-volatile feature ensures system stability after power cycles, making it suitable for embedded systems requiring persistent configuration data.

Digital Potentiometers Replacement Considerations

Direct replacements include other CAT5114 variants with different resistance values or packages, such as CAT5114VI-10-GT3 (SOIC) or CAT5114LI-00-G (PDIP). Cross-reference pinouts and electrical characteristics to ensure compatibility with existing circuit designs.
