MIC Click Board™

Product Code: MIKROE-2563

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.

2Maximum specifications are measured at maximum VDD. Typical specifications are measured at VDD=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.
