Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for end-of-life notifications as availability may be restricted. Ensure packaging specifications match design requirements.

Digital Potentiometers Selection Notes

Select this component when non-volatile memory is required for wiper position retention. Verify that the 3-wire serial interface aligns with available microcontroller pins. Ensure the 10 kOhm resistance value fits the circuit impedance requirements. Confirm TSSOP-8 package compatibility with PCB footprint.

Digital Potentiometers Part Context

This part belongs to the CAT5114 series of digitally programmable potentiometers. It shares architectural similarities with other CAT51xx devices but is distinguished by its specific tap count, interface type, and non-volatile memory configuration. It serves as a solid-state alternative to mechanical potentiometers in space-constrained designs.
