SETUP SUMMARY
The transfer condition of Figure 2 has been implemented. For
inputs below the 100 μV noise gate threshold, circuit and back-
ground noise is minimized. Above it, the output increases at a
rate of 1 dB for each 2 dB input increase until the 500 mV rotation
point is reached at an input of approximately 15 mV. For higher
inputs that drive the output beyond 500 mV, limiting occurs
and there is little further increase. The SSM2166 processes the
output of the buffer, which in the previous example is 20 dB, or
10× the input level. Use the oscilloscope to ensure that the
buffer is not being driven into clipping with the highest expected
input peaks. Always take the minimum gain in the buffer consis-
tent with the average source level and crest factor (ratio of peak
to rms). The wide program range of the SSM2166 makes it
useful in many applications other than microphone signal
conditioning.
