Overview
The AAP661AS-M5A-GLF-TR is a mono electret microphone pre-amplifier manufactured by Microchip Technology. It operates within a supply voltage range of 1.6V to 5.5V and provides a fixed gain of 16dB. The device integrates a programmable filter for signal conditioning. It is housed in a compact 5-WLCSP package, suitable for surface-mount applications. The component functions as a Class A amplifier and is designed for low-power audio input stages.
Feature Summary
- Integrated programmable filter for customized frequency response
- Fixed 16dB gain configuration for electret microphones
- Low-voltage operation supporting 1.6V to 5.5V supplies
Applications
- Mobile phone audio input circuits
- Voice recognition module front-ends
- Portable digital recording devices
Procurement Notes
Verify the specific suffix 'AS' confirms the 16dB gain variant, distinct from other gain options in the family. Confirm the WLCSP-5 package footprint matches the PCB design. Ensure the tape and reel quantity aligns with production requirements. Check RoHS compliance status if required by local regulations.
Selection Notes
Select this part when a fixed 16dB gain is required for electret microphones. Compare against the AAP661CS variant if 30dB gain is needed instead. Consider the WLCSP-5 package size constraints relative to available board space. Verify supply voltage compatibility with the target system's power rails.
Part Context
This component belongs to the AAP661 series of electret microphone pre-amplifiers. The series offers various gain configurations and package options. The AS suffix denotes the specific 16dB gain version. The M5A indicates the 5-ball WLCSP package type. GLF typically signifies lead-free and halogen-free construction.
Replacement Considerations
The AAP661CS-M5A-GLF-TR is a confirmed substitute within the same family but provides 30dB gain instead of 16dB. Verify if the increased gain meets the application requirements. Other variants may differ in package or gain settings.
