The document details a design for a dual-channel voltage-controlled amplifier with a dynamic range of 55 dB, a 3-dB bandwidth of 8 MHz, and exponential control. The circuit utilizes an AD539 dual multiplier chip connected in series with two AD827 high-speed operational amplifiers acting as current-to-voltage converters.
The amplifier has a dynamic range of 55 dB.
The circuit has a 3-dB bandwidth of 8 MHz.
The output ranges from 5 mV p-p at Vx = 0V to 3V p-p at Vx = 3V.
