if yes by how much?
As with most any analog or digital IC, we recommend using a bypass capacitor between Vdd and ground. Without this capacitor, the microphone's performance could be degraded. This could include a reduction in SNR, although I'm not able to quantify by exactly how much. That would depend on the specific design.
Thank you for your post. Which product are you referring to?
ADMP521 MEMS Dig mic.
I moved this question about the ADMP521 to the Audio Community. Someone here should be able to assist you.
