FEATURES  
DESCRIPTION

•
3V OPERATION  
The VCA8617 is an 8-channel variable gain amplifier  
ideally suited to portable ultrasound applications.  
Excellent dynamic performance enables use in  
low-power, high-performance portable applications.  
Each channel consists of a 20dB gain Low-Noise  
pre-Amplifier (LNA) and a Variable Gain Amplifier  
(VGA). The differential outputs of the LNA can be  
switched through the 8x10 cross-point switch, which  
is programmable through the serial interface input  
port.

LOW INPUT NOISE:  
–

INTEGRATED INPUT CLAMP DIODES  
DIFFERENTIAL OUTPUT  
The output of the LNA is fed directly into the VGA  
stage. The VGA consists of two parts,  
Voltage-Controlled Attenuator (VCA) and  
a
a
INTEGRATED INPUT LNA  
Programmable Gain Amplifier (PGA). The gain and  
gain range of the PGA can be digitally configured  
separately. The gain of the PGA can vary between  
four discrete settings of 25dB, 30dB, 35dB, and  
40dB. The VCA has four programmable maximum  
attenuation settings: 29dB, 33dB, 36.5dB, and 40dB.  
Also, the VCA can be continuously varied by a control  
voltage from 0dB to a maximum of 29dB, 33dB,  
36.5dB, and 40dB.  
READABLE CONTROL REGISTERS  
INTEGRATED CONTINUOUS WAVE (CW)  
PROCESSOR  
The output of the PGA feeds directly into an  
integrated low-pass filter.
