DESCRIPTION  
The VCA610 is a wideband, continuously variable,  
voltage-controlled gain amplifier. It provides  
linear-dB gain control with high impedance inputs.  
It is designed to be used as a flexible gain-control  
element in a variety of electronic systems.  
The VCA610 is designed with a very fast overload  
recovery time of only 200ns. This allows a large  
signal transient to overload the output at high gain,  
without obscuring low-level signals following closely  
behind. The excellent overload recovery time and  
distortion specifications optimize this device for low-  
level doppler measurements.  
The VCA610 has a gain-control range of 77dB  
(–38.5dB to +38.5dB) providing both gain and attenu-  
ation for maximum flexibility in a small SO-8. The  
broad attenuation range can be used for gradual or  
controlled channel turn-on and turn-off for applica-  
tions in which abrupt gain changes can create artifacts  
or other errors. In addition, the output can be disabled  
to provide –77dB of attenuation. Group delay varia-  
tion with gain is typically less than ±2ns across a  
bandwidth of 1MHz to 15MHz.

The VCA610 has a noise figure of 3.5dB (with an RS  
of 200) including the effects of both current and  
voltage noise. Instantaneous output dynamic range is  
70dB for gains of 0dB to +38.5dB with 1MHz noise  
bandwidth. The output is capable of driving 100.  
The high-speed, 300dB/µs, gain-control signal is a  
unipolar (0V to –2V) voltage that varies the gain  
linearly in dB/V over a –38.5dB to +38.5dB range.
