The VCA821ID is a DC-coupled wideband linear in dB continuously variable voltage-controlled Gain Amplifier provides a differential input to single-ended conversion with a high-impedance gain control input used to vary the gain down 40dB from the nominal maximum gain set by the gain resistor (RG) and feedback resistor (RF). The VCA821 device internal architecture consists of two input buffers and an output current feedback amplifier stage integrated with a multiplier core to provide a complete variable gain amplifier (VGA) system that does not require external buffering. The maximum gain is set externally with two resistors, providing flexibility in designs. The maximum gain is intended to be set between 6 and 32dB. Operating from ±5V supplies, the gain control voltage for the VCA821 device adjusts the gain linearly in dB as the control voltage varies from 0 to +2V. The VCA821 device offers excellent gain linearity.
