MP23AB02BTR

Microphones Overview

The MP23AB02BTR is a MEMS audio sensor and high-performance analog bottom-port microphone manufactured by STMicroelectronics. It features a compact, low-power design with a low-profile sensing element capable of detecting acoustic waves. The device operates within a supply voltage range of 1.6 V to 3.6 V and supports an audio frequency response from 20 Hz to 20 kHz. It provides a signal-to-noise ratio of 64 dB and utilizes a RHLGA-3 package for omnidirectional sound capture.

Microphones Feature Summary

• Omnidirectional acoustic detection via a low-profile sensing element
• High-performance analog output suitable for audio applications
• Low-power consumption design for portable devices

Microphones Applications

• Mobile phones and smartphones
• Tablets and portable media players
• Voice recognition systems

Microphones Procurement Notes

Verify the specific suffix 'BTR' corresponds to the required tape-and-reel packaging configuration when ordering. Confirm that the 1.6 V to 3.6 V operating voltage aligns with your system's power rails. Ensure compatibility with the RHLGA-3 footprint during PCB layout. Cross-reference the datasheet revision date to confirm technical specifications have not changed in newer releases.

Microphones Selection Notes

Select this component for applications requiring a small form factor and low power usage. The bottom-port design facilitates integration into thin enclosures. The 64 dB SNR offers adequate performance for standard voice recording tasks. Consider the analog interface requirement, as digital alternatives may be needed for direct MCU connection without additional ADC stages.

Microphones Part Context

This part belongs to STMicroelectronics' MEMS microphone portfolio, designed for consumer electronics. It complements other audio sensors in the lineup by offering a balance between size, power efficiency, and acoustic performance. The product targets the mobile and wearable technology sectors where space constraints are critical.

Microphones Replacement Considerations

Check for pin-compatible alternatives within the same series if supply chain issues arise. Verify that any substitute maintains the same RHLGA-3 package dimensions and electrical characteristics. Consult official substitution guides for validated cross-references.
