MAX2077
Octal-Channel Ultrasound Front-End
______________________________________________________________________________________

Detailed Description
The MAX2077 is a high-density, octal-channel ultra-
sound receiver optimized for low-cost, high-channel
count, high-performance portable and cart-based ultra-
sound applications. The integrated octal LNA, VGA,
and AAF offer a complete ultrasound imaging path
receiver solution.
Imaging path dynamic range has been optimized for
exceptional second-harmonic performance. The com-
plete imaging receive channel exhibits an exceptional
68dBFS* SNR at 5MHz. The bipolar front-end has also
been optimized for exceptionally low near-carrier mod-
ulation noise for exceptional low-velocity pulsed and
color-flow Doppler sensitivity under high-clutter condi-
tions, achieving an impressive near-carrier SNR of
140dBc/Hz at 1kHz offset from a VOUT = 1VP-P, 5MHz
clutter signal. To add CW Doppler capability, replace
the MAX2077 with the MAX2078.
Modes of Operation
The MAX2077 requires programming before it can be
used. The operating modes are controlled by the
D0–D6 programming bits. Tables 1 and 2 show the
functions of these programming bits.
Low-Noise Amplifier (LNA)
The MAX2077’s LNA is optimized for excellent dynamic
range and linearity performance characteristics, mak-
ing it ideal for ultrasound imaging applications. When
the LNA is placed in low-gain mode, the input resis-
tance (RIN), being a function of the gain A (RIN =
RF/(1+A)), increases by a factor of approximately 2.
