Description

1.Description:

 It is a SSM2167 preamplifier.SSM2167 is a low-voltage,low-noise mono microphone preamplifier,very suitable for low-power audio signal chains.

2.Feature:

 1).SSM2167 is a low-voltage,low-noise mono microphone preamplifier,very suitable for low-power audio signal chains.

 2).The preamplifier includes built-in compression and noise gates,which is better than using only an operational amplifier in the preamplifier circuit for this function.

 3).Compressing the dynamic range of the microphone signal reduces the peak signal level and adds extra gain to low-level signals.

 4).The noise threshold attenuates the signal level below a certain threshold in order to only amplify the desired signal,such as speech,and reduce the noise in the output signal.
