General Description
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-
ure at RS = RIN = 200Ω at a very low 64.8mW per-
channel power dissipation. The full imaging receiver
channel has been optimized for second-harmonic
imaging with -64dBFS second-harmonic distortion per-
formance with a 1VP-P 5MHz output signal and broad-
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-
set from a 5MHz 1VP-P output clutter signal.
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.
