•
710MHz SMALL-SIGNAL BANDWIDTH  
(G = +2V/V)  
The VCA824 is a dc-coupled, wideband, linear in V/V,  
continuously variable, voltage-controlled gain  
amplifier. It provides 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).

> 40dB GAIN ADJUST RANGE  
HIGH GAIN ACCURACY: 20dB ±0.3dB  
HIGH OUTPUT CURRENT: ±90mA  
The VCA824 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 +2V/V and +40V/V. Operating from  
±5V supplies, the gain control voltage for the VCA824  
adjusts the gain linearly in V/V as the control voltage  
varies from +1V to –1V. For example, set for a  
maximum gain of +10V/V, the VCA824 provides  
10V/V, at +1V input, to 0.1V/V at –1V input of gain  
control range. The VCA824 offers excellent gain
