Abstract
A 2-chip MEMS microphone component includes: at least one first MEMS microphone structural component having at least one first microphone structure formed in the front side of the structural component; an ASIC structural component having evaluation electronics for the microphone signal of the MEMS microphone structural component; and a housing having a sound opening. The MEMS microphone structural component is mounted within the housing and above the sound opening in such a way that the rear side of the microphone structure is acted on by the sound pressure. The ASIC structural component also includes a second MEMS microphone structure whose microphone signal is fed to the evaluation electronics.
