Frequently Asked Questions
What is relates to SPM0408LE5H?
The SPM0408LE5H has a sensitivity of -42dBV, which is suitable for most voice applications. This sensitivity level provides good signal levels for subsequent amplification and processing. Contact BeiLuo FAE team for additional guidance and support.
Verify sensitivity matches your amplifier gain requirements.
How do I interface SPM0408LE5H with my audio codec?
The SPM0408LE5H analog output connects directly to the microphone input of your audio codec. Use AC coupling capacitors (typically 1-10μF) between the microphone output and codec input. Provide clean power supply with proper decoupling capacitors. Contact BeiLuo FAE team for additional guidance and support.
Ensure your codec has appropriate microphone input and bias voltage.
What is the maximum SPL of SPM0408LE5H?
The SPM0408LE5H can handle up to 120dB SPL (Sound Pressure Level) without significant distortion. This is sufficient for most consumer electronics applications. For higher SPL requirements, consider other Goertek microphone models. Contact BeiLuo FAE team for additional guidance and support.
Verify maximum SPL meets your application requirements.
How does SPM0408LE5H compare to Knowles microphones?
The SPM0408LE5H offers competitive performance compared to similar Knowles analog MEMS microphones. It provides equivalent SNR and sensitivity specifications at a more competitive price point. The package size and pinout are industry-standard for easy substitution. Contact BeiLuo FAE team for additional guidance and support.
Cost-effective alternative to Knowles microphones.
What is the lead time for SPM0408LE5H?
Standard lead time for SPM0408LE5H is 8-12 weeks for production quantities. Sample quantities are typically available from stock with 1-2 week delivery. For high-volume projects, scheduled deliveries can be arranged with 4-6 week lead time. Contact BeiLuo FAE team for additional guidance and support.
