... AD1845 and AD1847. The device is available in 8-lead SOIC and P-DIP packages, and guaranteed for operation over the extended industrial temperature range of – + shown in Figure 1a, the SSM2165-1 has a rotation point of –25.7 dBu (40 mV) and gives –7.7 dBu (320 mV) before limiting. As shown in Figure 1b, the SSM2165-2 has a rotation point of – ...

... SSM2165-1P – +85 C Plastic DIP SSM2165-1S – +85 C Narrow SOIC SSM2165-2S – +85 C Narrow SOIC Not for new design, obsolete April 2002. 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 SSM2165 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges ...

... A downward expansion (noise gating) feature reduces background and circuit noise below 500 V. The rotation point determines the output signal levels before limiting (referred to the input), and for the SSM2165-1 and 100 mV for the SSM2165-2. LIMITING THRESHOLD ...

... C3 GND 22 F The bandwidth of the SSM2165 is quite wide at all gain set- tings. The upper –3 dB point is approximately 300 kHz. The GBW plots are shown in TPC 5. While the noise of the input buffer is fixed, the input referred noise of the VCA is a function of gain ...

... The rotation point determines the output level above which limiting occurs. That is, in the limiting region change of input results change of output. The rotation point is set (–26 dBu) for the SSM2165-1 and 100 mV (–18 dBu) for the SSM2165-2. In the SSM2165, limiting is compression at a fixed compression ratio of approxi- mately 15:1 ...

... Reduce the input gradually until the output falls off more rapidly. This point is the noise gate threshold, and should be approximately 500 V (–64 dBu). The noise gate threshold on the SSM2165 is fixed at 500 V, a practical value for many microphones. Should a different noise gate threshold be required, consider using the SSM2166. ...

... Power-down and mute functions are also built in. Custom- ized versions of the SSM2165 are available for large volume LIMITING REGION 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.
