Digital Potentiometers Procurement Notes

Verify the specific suffix 'EP' indicates military-grade qualification or controlled baseline manufacturing when sourcing. Confirm RoHS3 compliance status matches project requirements. Ensure the 20-TSSOP footprint aligns with PCB design constraints. Validate that the I2C address configuration meets system topology needs before finalizing procurement.

Digital Potentiometers Selection Notes

Select this component when four isolated digital potentiometers are required in a single package. The 10k Ohm resistance value suits moderate impedance applications. The I2C interface minimizes pin count compared to parallel interfaces. Non-volatile storage eliminates the need for external EEPROMs to save calibration data.

Digital Potentiometers Part Context
