The VCA824 is a DC-coupled, wideband, linear-in V/V, continuously variable, voltage-controlled gain amplifier. The device 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).

TI’s VCA824 is a Wideband 420MHz, >40dB Gain Adjust Range, Linear in V/V Variable Gain Amplifier. Find parameters, ordering and quality information.
