SMO07C-38/1348

Overview

The SMO07C-38/1348 is an analog MEMS microphone manufactured by BeStar Technologies, Inc. It features a silicon-based omnidirectional capsule with a sensitivity of -38dB ±1dB. The device operates within a voltage range of 1.9 V to 3 V and supports a frequency response from 100 Hz to 10 kHz. Key electrical specifications include a signal-to-noise ratio of 70dB and an impedance of 400 Ohms. The component is supplied in box packaging and is currently active.

Feature Summary

• Omnidirectional acoustic design for uniform sound capture
• Silicon MEMS construction for durability
• Low voltage operation capability

Applications

• Consumer audio recording devices
• Voice recognition systems
• Portable electronic equipment

Procurement Notes

Verify the specific suffix /1348 against official BeStar documentation to confirm packaging and revision details. Ensure compatibility with 1.9V to 3V supply rails. Confirm solder pad requirements for surface mount assembly. Check for RoHS compliance status in the latest datasheet.

Selection Notes

Select this component when an omnidirectional analog output is required for low-voltage applications. The -38dB sensitivity suits general voice pickup rather than high-fidelity studio use. Verify that the 400 Ohm impedance matches the input stage of the connected amplifier or ADC circuitry.

Part Context

This part belongs to the BeStar Technologies MEMS microphone family. It utilizes silicon micromachining technology to create a compact acoustic sensor. The series focuses on cost-effective solutions for mass-market electronics requiring reliable voice input capabilities.

Replacement Considerations

Cross-reference with other BeStar models such as SPM04C-38/1186 for similar sensitivity profiles. Verify pinout and package dimensions before substituting with components from other manufacturers to ensure mechanical fit.
