Procurement Notes
This component has reached end-of-life status and is officially discontinued by the manufacturer. Availability is limited to existing stock or secondary market sources. Verify authenticity and storage conditions carefully when sourcing from non-direct suppliers. Design-in activities should consider alternative replacement parts due to long-term supply constraints.
Selection Notes
Engineers requiring this specific acoustic profile must evaluate obsolete part risks. The fixed 300 Ohm impedance and 350µA current draw define the biasing requirements. Ensure the application circuit supports the 1.5V to 3.6V operating range. Consider the 100 Hz to 8 kHz bandwidth limitation against target voice frequency requirements before finalizing the design.
Part Context
Part of the SiSonic™ family of silicon microphones, the SP0408LE5H-SB represents an earlier generation of analog MEMS technology from Syntiant. It utilizes a top-port configuration and solder pad termination. This model serves as a foundational component in legacy audio hardware designs prior to the industry shift toward digital PDM interfaces.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, no official cross-reference data is listed.
