... Figures 10 through 12 show distortion vs. signal level for the three parts in the 2180 Series for 0 dB, +15 dB and -15 dB gain. The circuit of Figure 2, Page 3 was used to generate these curves. For a specific application, the acceptable distor- tion will usually determine the maximum signal current level which may be used ...

... R /R for an inverting opamp will f i determine the overall voltage gain when the 2180 is set for 0 dB current gain. Since the VCA performs best at settings near unity gain, use the input and feedback resistors to provide design-center gain or loss, if necessary. ...

... This can become significant if care is not taken to drive the control ports with quiet signals. The 2180 Series VCAs have a small amount of inherent noise modulation because of its class AB biasing scheme, where the shot noise in the core transistors reaches a minimum with no signal, and ...
