MAX2034
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 19d B fixed gain, and a wide -3d B bandwidth of 70MHz. The high-gain accuracy of the amplifier allows for exceptional channel-to-channel gain matching, which is necessary for high-performance ultrasound-imaging applications. The MAX2034 also includes an on-chip programmable input impedance feature that allows the device to be patible with a variety of mon source impedances ranging from 50Ω to 1kΩ. The input impedance of each amplifier uses a feedback topology for active impedance matching. The active input impedance matching feature achieves an exceptionally low 2.2d B noise figure with a source and input impedance of 200Ω.
The MAX2034 has excellent dynamic and linearity performance characteristics optimized for all ultrasoundimaging modalities including...
