1 / 13 page 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 50Ω to 1kΩ. 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 200Ω. 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 VOUT = 1VP-P and fIN = 5MHz, and an ultrasound-spe- cific* two-tone third-order intermodulation distortion per- formance of -55dBc at VOUT = 1VP-P and fIN = 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.
