Preliminary Technical Data

MATCHED MICROPHONE PAIRS
WM7121 and WM7132 are sensitivity matched microphone pairs.
The enhanced versions,
WM7121E and WM7132E have tight tolerance of ±1dB and compatible output performance. These
microphones are ideal for accurate sound pickup from opposite directions in slim profile applications.
WM7121E should be positioned close to WM7132E on the same side of the PCB to maximise
acoustic matching for effective DSP application.
The WM7121 and WM7132 also have matched frequency response at both high and low frequencies,
allowing simplified system design.
