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 that the GAIN input ...
