gain range of the PGA can be digitally configured separately. The  
gain of the PGA can be varied between two discrete settings of  
21dB and 26dB. 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.  
DESCRIPTION  
The VCA8613 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 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.  
The output of the PGA feeds directly into an integrated  
2-pole, low-pass filter, allowing for direct connection to a  
differential input Analog-to-Digital Converter (ADC), such as  
the ADS5121 or ADS5122 from Texas Instruments. The  
VCA8613 is available in a TQFP-64 package.  
The output of the LNA is fed directly into the VGA stage. The  
VGA consists of two parts, a Voltage Controlled Attenuator  
(VCA) and a Programmable Gain Amplifier (PGA). The gain and
