SPK01A0LR5H-1-7

Overview

The SPK01A0LR5H-1-7 is a high Signal-to-Noise Ratio (SNR) and high Acoustic Overload Point (AOP) analog bottom port silicon microphone from the SiSonic series. It operates on a supply voltage range of 2.3 V to 3.6 V with a typical current consumption of 180 µA. The device features an omnidirectional frequency response spanning 17 Hz to 16 kHz. It utilizes solder pads for surface mount assembly in a compact form factor measuring 4.00 mm by 3.00 mm.

Feature Summary

• High signal-to-noise ratio performance for clear audio capture
• High acoustic overload point capability for handling loud sound sources
• Bottom port design optimized for specific acoustic chamber integration

Applications

• Voice recognition systems requiring high fidelity input
• Smart home devices and voice assistants
• Mobile communication handsets
• Wearable audio technology

Procurement Notes

Verify that the ordering suffix '-7' corresponds to the correct cut tape packaging variant rather than reel quantities. Confirm the specific SNR and AOP values against the manufacturer's datasheet for the exact lot, as these parameters define the component's acoustic performance tier. Ensure the bottom port orientation aligns with the target application's acoustic path design.

Selection Notes

Select this component when high SNR and high AOP are critical requirements for the audio front end. The analog output interface necessitates compatible ADC inputs or pre-amplification stages. Evaluate the 180 µA current draw against battery life constraints for portable applications. The 4.00 mm x 3.00 mm footprint must fit within the mechanical enclosure limits alongside other PCB components.

Part Context

This part belongs to Syntiant's SiSonic MEMS microphone family, which focuses on advanced acoustic sensing solutions. The SPK01A0LR5H-1-7 represents the analog output variant designed for general-purpose voice capture. It complements digital PDM microphones in the portfolio by providing direct analog signal availability for legacy or specific mixed-signal processing architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Syntiant models such as SPK01A0LR5H-1 for potential functional compatibility if packaging differences exist.
