EVALUATION BOARD EXAMPLES
To illustrate how easy it is to program the SSM2166, a practical
example is provided. The SSM2166 was used to interface an
electret-type microphone to a postamplifier. The evaluation
board or the circuit configuration shown in Figure 26 can be
used. The signal from the microphone was measured under
actual conditions to vary from 1 mV to 15 mV. The postamplifier
requires no more than 500 mV at its input. The required gain
from the SSM2166 is, therefore
GTOTAL = 20 × log(500/15) = 30 dB
The input buffer gain is set to 20 dB, and the VCA gain is adjusted
to 10 dB. The limiting or rotation point is set at 500 mV output.
A 2:1 compression ratio and a noise gate threshold that operates
below 100 V is also used. These objectives are summarized in
Table 5. The transfer characteristic implemented is illustrated in
Table 5. Objective Specifications
