MIC Click Board

Product Description

The MIC Click Board™ carries the SPQ0410HR5H-B surface mount silicon microphone with maximum RF protection. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over the AN pin on the mikroBUS™ line.

How Does The MIC Click Board™ Work?

The MIC Click Board™ contains a silicon microphone, which outputs the signal to the analog pin (AN) on the mikroBUS™ line via the op amp.

SPQ0410HR5H-B FEATURES

The SPQ0410HR5H-B is a miniature, high-performance, low power, top port silicon microphone.

Using the SiSonic™ MEMS technology, the SPQ0410HR5H-B consists of an acoustic sensor, a low noise input buffer, and an output amplifier.

MaxRF protection prevents RF noise in traces from getting into the mic output.

TEST CONDITIONS: 23 ± 2C °, 55 ± 20 % R.H., V_DD(min)<V_DD(max), no load, unless otherwise indicated

¹100% tested.
²Maximum specifications are measured at maximum V_DD. Typical specifications are measured at V_DD=1.8V.

OMNIDIRECTIONAL MICROPHONES

SPQ0410HR5H-B is an omnidirectional microphone. As the name implies an omnidirectional microphone can hear equally in all directions. So whichever way you hold it, up or down, it will work the same.
