SBOS185D – JANUARY 2001 – REVISED MARCH 2003  
Dual, VARIABLE GAIN AMPLIFIER  
with Input Buffer  
FEATURES  
● GAIN RANGE: 40dB  
DESCRIPTION  
The VCA2614 is a highly integrated, dual receive channel,  
Variable Gain Amplifier (VGA) with analog gain control.  
● 40MHz BANDWIDTH  
The VCA2614’s VGA section consists of two parts: the Volt-  
age Controlled Attenuator (VCA) and the Programmable Gain  
Amplifier (PGA). The gain and gain range of the PGA can be  
digitally programmed. The combination of these two program-  
mable elements results in a variable gain ranging from 0dB up  
to a maximum gain as defined by the user through external  
connections. The single-ended unity gain input buffer provides  
predictable high input impedance. The output of the VGA can  
be used in either a single-ended or differential mode to drive  
high-performance Analog-to-Digital Converters (ADCs). A sepa-  
rate power-down pin reduces power consumption.  
● LOW CROSSTALK: 70dB at Max Gain, 5MHz  
● HIGH-SPEED VARIABLE GAIN ADJUST  
● POWER SHUTDOWN MODE  
● HIGH IMPEDANCE INPUT BUFFER  
APPLICATIONS  
● ULTRASOUND SYSTEMS  
● GAMMA CAMERAS  
● WIRELESS RECEIVERS  
● TEST EQUIPMENT  
The VCA2614 also features low crosstalk and outstanding  
distortion performance. The combination of low noise and gain  
range programmability makes the VCA2614 a versatile build-  
ing block in a number of applications where noise perfor-  
mance is critical. The VCA2614 is available in a TQFP-32  
package.
