AAP661CS-M5A-GLF-TR

Overview

The AAP661CS-M5A-GLF-TR is an electret microphone pre-amplifier manufactured by Microchip Technology. It features a programmable filter and provides a fixed gain of 30dB. The device is housed in a 5-ball Wafer Level Chip Scale Package (WLCSP). It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrated electret microphone pre-amplification circuitry
• Configurable signal filtering capabilities
• Compact wafer-level chip scale packaging for space-constrained designs

Applications

• Voice recognition modules
• Smart home audio devices
• Portable consumer electronics with microphone input

Procurement Notes

Verify the specific suffix 'CS' confirms the 30dB gain variant, as other suffixes like 'AS' indicate different gain levels. Ensure the WLCSP package type matches the PCB footprint requirements. Confirm the operating temperature range meets the target application environment specifications before finalizing procurement.

Selection Notes

Select this component when a low-profile solution for electret microphones is required. The 30dB gain setting suits applications needing moderate signal amplification. Consider the WLCSP form factor for high-density board layouts where traditional packages are unsuitable.

Part Context

This part belongs to Microchip's line of audio interface components designed for embedded voice applications. It serves as a bridge between analog microphone sensors and digital processing units, simplifying system architecture by integrating amplification and filtering functions into a single small-footprint device.

Replacement Considerations

The AAP661AS-M5A-GLF-TR is a related variant offering 16dB gain instead of 30dB. Substitution requires verifying if the lower gain level meets the system's signal-to-noise ratio requirements. Other gain configurations may exist within the same family.
