Octal-Channel Ultrasound Front-End  
MAX207  
General Description  
Features  
o 8 Full Channels of LNA, VGA, and AAF in a Small,  
8mm x 8mm, 56-Pin or 10mm x 10mm, 68-Pin  
TQFN Package  
The MAX2077 octal-channel ultrasound front-end is a  
fully integrated, bipolar, high-density, octal-channel  
ultrasound receiver optimized for low-cost, high-chan-  
nel count, high-performance portable and cart-based  
ultrasound systems. The easy-to-use IC allows the user  
to achieve high-end 2D and PW imaging capability  
using substantially less space and power. The highly  
compact imaging receiver lineup, including a low-noise  
amplifier (LNA), variable-gain amplifier (VGA), and anti-  
alias filter (AAF), achieves an ultra-low 2.4dB noise fig-  
o Ultra-Low Full-Channel Noise Figure of 2.4dB at  
RIN = RS = 200Ω  
Hz  
o Low Output-Referred Noise of 23nV/√ at 5MHz,  
20dB Gain, Yielding a Broadband SNR of 68dB*  
for Excellent Second-Harmonic Imaging  
o High Near-Carrier SNR of 140dBc/Hz at 1kHz  
Offset from a 5MHz, 1VP-P Output Signal, and  
20dB of Gain for Excellent Low-Velocity PW and  
Color-Flow Doppler Sensitivity in a High-Clutter  
Environment

channel power dissipation. The full imaging receiver  
channel has been optimized for second-harmonic  
imaging with -64dBFS second-harmonic distortion per-

band SNR of > 68dB* at 20dB gain. The bipolar  
front-end has also been optimized for excellent low-  
velocity PW and color-flow Doppler sensitivity with an  
exceptional near-carrier SNR of 140dBc/Hz at 1kHz off-  
o Selectable Active Input-Impedance Matching of  
50Ω, 100Ω, 200Ω, and 1kΩ  
o Wide Input-Voltage Range of 330mVP-P in High LNA  
Gain Mode and 550mVP-P in Low LNA Gain Mode  
set from a 5MHz 1V  
output clutter signal.  
P-P  
o Integrated Selectable 3-Pole 9MHz, 10MHz,  
The MAX2077 octal-channel ultrasound front-end is  
available in a small 8mm x 8mm, 56-pin thin QFN or  
10mm x 10mm, 68-pin thin QFN package with an  
exposed pad and is specified over a 0°C to +70°C tem-  
perature range. To add CW Doppler capability, replace  
the MAX2077 with the MAX2078.  
15MHz, and 18MHz Butterworth AAF  
o Fast-Recovery, Low-Power Modes (< 2µs)  
o Pin Compatible with the MAX2078 Ultrasound
