SHIKUES|Silicon microphone HGM42A

HGM42A is a high-quality, low-cost, low-power analog output forward omnidirectional MEMS microphone. HGM42A consists of a MEMS microphone element and a front-end amplifier. HGM42A has a high SNR and a flat broadband frequency response, which has a high Clear natural sound. Thanks to the built-in filter, the HGM42A uses an LGA metal case and is surface mounted, which makes reflow compatible without reducing sensitivity.

Applications: Walkie-talkies, mobile phones, smart desk lamps, smart fans, smart homes, smart Bluetooth speakers, robot learning machines, voice navigation systems and other products.

typical application:

The HGM42A output can be connected to the codec microphone input or a high input impedance gain stage. A DC blocking capacitor is required at the output of the microphone.
