SSM2167 Microphone Front Amplifier
Product Introduction:
The SSM2167 is a low-voltage, low-noise mono microphone preamplifier that is perfect for low-power audio signal links. The preamplifier includes built-in compression and noise gate, which is superior to using only operational amplifiers in the preamplifier circuit for this function. Compressing the dynamic range of the microphone signal can reduce the peak signal level and add additional gain to low-level signals. The noise threshold attenuates the signal level below a specific threshold in order to amplify only the desired signal, such as speech, and reduce noise within the output signal. These characteristics help improve the clarity of the speech signal received by the microphone.
R1 and R2 can be changed as needed, and a plug-in pad is reserved next to the SMD resistor, allowing for the use of plug-in resistors.
Working voltage: DC 3V~5V
Board size: 23mm * 15mm
