FEATURES  
DESCRIPTION  
The VCA5807 is an integrated Voltage Controlled  
Amplifier (VCA) specifically designed for ultrasound  
systems in which high performance and small size  
are required. The VCA5807 integrates a complete

continuous wave Doppler (CWD) path. It also enables  
users to select one of various power/noise  
combinations to optimize system performance.  
Therefore, the VCA5807 is a suitable ultrasound  
analog front end solution not only for high-end  
systems, but also for portable systems.

•
40 dB Low Noise Voltage Controlled  
Attenuator (VCAT)  
The VCA5807 contains eight channels of voltage  
controlled amplifier (VCA), and CW mixer. The VCA  
includes Low noise Amplifier(LNA), Voltage controlled  
Attenuator (VCAT), Programmable Gain Amplifier  
(PGA), and Low-Pass Filter (LPF). The LNA gain is  
programmable to support 250 mVPP to 1 VPP input  
signals. Programmable active termination is also  
supported by the LNA. The ultra-low noise VCAT  
provides an attenuation control range of 40dB and  
improves overall low gain SNR which benefits  
harmonic imaging and near field imaging. The PGA  
provides gain options of 24 dB and 30 dB. Before the  
ADC, a LPF can be configured as 10 MHz, 15 MHz,  
20 MHz, or 30 MHz to support ultrasound  
applications with different frequencies. In addition, the  
signal chain of the VCA5807 can handle signal  
frequency lower than 100 KHz, which enables it to be  
used not only in ultrasound applications but also in  
sonar applications.

Passive Mixer for Continuous Wave Doppler  
(CWD)  
The VCA5807 integrates a low power passive mixer  
and a low noise summing amplifier to accomplish on-  
chip CWD beamformer. 16 selectable phase-delays  
can be applied to each analog input signal.  
Meanwhile a unique 3rd and 5th order harmonic  
suppression filter is implemented to enhance CW  
sensitivity.
