Overview
The SPW1442HR5H is a SiSonic MEMS microphone manufactured by Syntiant. It features an analog output and top-port acoustic design. The device operates within a supply voltage range of 1.5 V to 3.6 V, drawing a typical operating current of 130 µA. It provides a sensitivity of -42 dB ± 1 dB at 94 dB SPL and achieves a signal-to-noise ratio (SNR) of 59 dB. The component supports a maximum sound pressure level (SPL) of 130 dB and offers a power supply rejection ratio (PSRR) of 66 dB. It utilizes an LGA-6 package with dimensions of 3.76 mm x 2.24 mm x 1.20 mm.
Feature Summary
- High signal-to-noise ratio performance for clear audio capture
- Top-port acoustic configuration for flexible board layout
- Low power consumption suitable for battery-operated devices
Applications
- Always-on voice activation systems
- Smart home voice assistants
- Hands-free communication modules
Procurement Notes
Verify the specific revision suffix and packaging type against the official datasheet before ordering. Confirm that the intended application environment falls within the specified operating temperature and voltage ranges. Ensure compatibility with existing PCB footprints and acoustic venting requirements. Check for any recent product change notices or end-of-life announcements from the manufacturer.
Selection Notes
Select this component when high SNR and low power are critical for always-on audio applications. Compare its top-port design against bottom-port alternatives based on mechanical constraints. Evaluate the 59 dB SNR against system noise floor requirements. Consider the LGA-6 footprint size relative to available board space.
Part Context
This part belongs to the Syntiant SiSonic family of MEMS microphones designed for deep-learning enabled audio processing. These components integrate acoustic sensing elements optimized for wake-word detection and speech recognition tasks in edge computing environments.
