General Description
The MAX2078 octal-channel ultrasound front-end is a
fully integrated bipolar, high-density octal-channel ultra-
sound receiver optimized for low cost, high-channel
count, high-performance portable and cart-based ultra-
sound systems. The easy-to-use IC allows the user to
achieve high-end 2D, PW, and CW Doppler (CWD)
imaging capability using substantially less space and
power. The highly compact imaging receiver lineup,
including low-noise amplifier (LNA), variable-gain
amplifier (VGA), and anti-alias filter (AAF), achieves an
ultra-low 2.4dB noise figure 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-har-
monic distortion performance with a 1VP-P 5MHz output
signal. 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 offset from a 5MHz 1VP-P output
clutter signal.
A fully integrated high-performance, programmable
CWD beamformer is also included. Separate I/Q mixers
for each channel are available for optimal CWD sensi-
tivity in high-clutter environments, yielding an impres-
sive near-carrier SNR of 154dBc/Hz at 1kHz offset from
a 1.25MHz 200mVP-P input clutter signal.
The MAX2078 octal-channel ultrasound front-end is
available in a small 10mm x 10mm, 68-pin thin QFN
package with an exposed pad and is specified over a
0°C to +70°C temperature range.
