Procurement Notes
Verify the specific package variant and tape/reel quantity directly with ETEK Microelectronics or authorized distributors before ordering. Confirm RoHS compliance status and lead times for the selected suffix. Ensure the procurement channel provides traceability documentation matching the manufacturer's part number.
Selection Notes
Select the ET5228 when low distortion and high speed are required for analog signal paths. Compare on-resistance flatness and bandwidth against alternative switches if signal fidelity at higher frequencies is critical. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
ETEK Microelectronics produces a range of analog switches and load management solutions. The ET5228 belongs to their portfolio of CMOS-based signal switching components, distinct from their LDO regulators and LED drivers. It serves as a general-purpose analog switch for consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers for the ET5228 were not found in the provided source material. Consult the official datasheet for recommended pin-compatible alternatives or contact the manufacturer for cross-reference information.
