... The flexibility of setting the compression ratio and the time constant of the level detector, coupled with two values of rotation point, make the SSM2167 easy to integrate in a wide variety of microphone conditioning applications. The device is available in a 10-lead MSOP package, and is guaranteed for operation over the extended industrial temperature range of − ...

... the SSM2167. The net gain from input to output can be as high as 40 dB, depending on the gain set by the control circuitry. The output impedance of the SSM2167 is typically less than 145 Ω, and the external load on Pin 9 should be >5 kΩ. The nominal output dc voltage of the device is approximately 1.4 V ...

... VCA GAIN should be considered for the PCB. The layout should minimize possible capacitive feedback from the output of the SSM2167 back to its input. Do not run input and output traces adjacent to each other. A single-point (star) ground implementation is recommended in addition to maintaining short lead lengths and PCB runs. In ...
