Working Voltage:DC 3V-5V
The SSM2167 is a low-voltage,low-noise mono microphone preamplifier,ideal for low-power audio signal chains.This preamplifier includes a built-in compression and noise gate,For this function,it is better than just using an op amp in the preamplifier circuit.The dynamic range of the compressed microphone signal reduces the peak signal level and adds additional gain to the low level signal.The noise gate attenuates the signal level below a certain threshold,in order to amplify only the desired signal,such as speech, and reduce the noise in the output signal.These features will help improve the clarity of the voice signal received by the microphone.
Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid
