SSM2165  
SUMMARY  
rms detector averaging time, and the decay time of the gate.  
Both compression ratio and decay time are usually determined  
by critical listening to the intended audio input.  
We have implemented the transfer characteristic of Figure 18.  
For inputs below the 500 µV noise gate threshold, circuit and  
background noise will be downward expanded (gain-reduced) at  
a ratio of approximately 1:3. That is, a –1 dB change in the  
noise will result in –3 dB decrease at the output. Above thresh-  
old, the signal will increase at a rate of 1 dB for each 2 dB input  
increase, until the rotation point is reached at an input of  
approximately 40 mV. In the limiting region, the compression  
ratio increases to approximately 15:1. That is, a 15 dB increase  
in input will produce a 1 dB increase at the output, so there will  
be little further increase for higher level inputs.  
STEP 7. Record Values  
With the power removed from the test fixture, measure and  
record the values of the RCOMP and CAVG.

The SSM2165 is an 8-lead version of the 14-lead SSM2166  
which is recommended for applications requiring more versatil-  
ity. The SSM2166 allows selection of noise gate threshold and  
rotation point, and allows the buffer to provide up to 20 dB of  
gain. Power-down and mute functions are also built in. Custom-  
ized versions of the SSM2165 are available for large volume  
users. The wide dynamic range of the SSM2165 makes it useful  
in many applications other than microphone signal conditioning  
such as a sustain generator for guitars. For further information,  
contact your Analog Devices representative.
