AD8337 THEORY OF OPERATION R G OVERVIEW The AD8337 is a low noise, single-ended, linear-in-dB, general- purpose, variable gain amplifier (VGA) usable at frequencies up to 100 MHz fabricated using a proprietary Analog Devices dielectrically isolated, complementary bipolar ...
Page 19
The gain scaling factor (gain slope) is designed for 20 dB/V; this relatively low slope ensures that noise on the GAIN input is not unduly amplified. Because a VGA functions as a multiplier important to make sure that ...

In the time domain, stray capacitance at the output pin can induce overshoot on the edges of transient signals, as seen in Figure 70 and Figure 72. The amplitude of the overshoot is also a function of the slewing of ...
