AD600/AD602 THEORY OF OPERATION The AD600 and AD602 have the same general design and features. They comprise two fixed gain amplifiers, each pre- ceded by a voltage-controlled attenuator 42.14 dB with independent control interfaces, each having ...
Page 7
The Gain-Control Interface The attenuation is controlled through a differential, high imped- ance (15 MΩ) input, with a scaling factor that is laser trimmed per volt, that is, 31.25 mV/dB. Each of the two amplifiers has its ...
