More Information

The VCA820 is a dc-coupled, wideband, linear in dB, continuously variable, voltage-controlled gain amplifier. The VCA820 provides a differential input to single-ended conversion with a high-impedance gain control input, used to vary the gain down 40 dB from the nominal maximum gain set by the gain resistor (RG) and feedback resistor (RF).
