Quad-Channel, Ultra-Low-Noise Amplifier with
Digitally Programmable Input Impedance
General Description
The MAX2034 four-channel, low-power, ultra-low-noise
preamplifier is designed for ultrasound and medical
instrumentation applications. Each low-noise amplifier
has a single-ended input, differential output, a highly
accurate 19dB fixed gain, and a wide -3dB bandwidth
of 70MHz. The high-gain accuracy of the amplifier
allows for exceptional channel-to-channel gain match-
ing, which is necessary for high-performance ultra-
sound-imaging applications. The MAX2034 also
includes an on-chip programmable input impedance
feature that allows the device to be compatible with a
variety of common source impedances ranging from
50 ? to 1k ? . The input impedance of each amplifier
uses a feedback topology for active impedance match-
ing. The active input impedance matching feature
achieves an exceptionally low 2.2dB noise figure with a
source and input impedance of 200 ? .
The MAX2034 has excellent dynamic and linearity per-
formance characteristics optimized for all ultrasound-
imaging modalities including second harmonic 2D
imaging and continuous wave Doppler. The device
achieves a second harmonic distortion of -68dBc at
V OUT = 1V P-P and f IN = 5MHz, and an ultrasound-spe-
cific* two-tone third-order intermodulation distortion per-
formance of -55dBc at V OUT = 1V P-P and f IN = 5MHz.
The MAX2034 is also optimized for quick overload
recovery for operation under the large input signal con-
ditions typically found in ultrasound input-buffer imag-
ing applications.
The MAX2034 is available in a 48-pin thin QFN pack-
age with an exposed paddle. Electrical performance is
guaranteed over a 0°C to +70°C temperature range.
