... 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 – ...

... F Figure 11. Functional Block Diagram and Typical Voice Application 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 Figure 6. 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 ...

... 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 you require a different noise gate threshold, consider using the SSM2166. ...

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