... SSM2167 easy to integrate in a wide variety of microphone conditioning applications. The SSM2167 is available in two versions, with different amounts of fixed gain. The SSM2167-1 has fixed gain, while the SSM2167-2 features only fixed gain. The device is available in 10-lead MSOP package, and guaranteed for operation over the extended industrial temperature range of – ...

... Exposure to absolute maximum rating condi- tions for extended periods may affect device reliability. Model SSM2167-1RM-Reel SSM2167-2RM-Reel Preliminary CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the SSM2167 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges ...

... The input buffer presents an input impedance of approximately R GATE 100 kΩ to the source voltage of approximately 1 present at INPUT (Pin 5 of the SSM2167), requiring the use COMP blocking capacitor (C1) for ground-referenced sources. A 0.1 µF capacitor is a good choice for most audio applications. The input buffer is a unity-gain stable amplifier that can drive the low imped- ance input of the VCA and an internal rms detector ...

... The bandwidth of the SSM2167 is quite wide at all gain settings. The upper 3 dB point is over 1 MHz at gains as high as 30 dB. The GBW plots are shown in TPC 3. The lower 3 dB cutoff frequency of the SSM2167 is set by the input impedance of the VCA (1 kΩ) and C2. While the noise of the input buffer is fixed, the input-referred noise of the VCA is a function of gain ...
