MAX2034 - Ultra-Low-Noise Amplifier

MAX2034 Description

19-3969; Rev 1; 3/07 MAX2034 Quad-Channel, Ultra-Low-Noise Amplifier with Digitally Programmable Input Impedance General .
The MAX2034 four-channel, low-power, ultra-low-noise preamplifier is designed for ultrasound and medical instrumentation applications.

MAX2034 Features

* High-Level Integration of 4 Channels
* Digitally Programmable Input Impedance (RIN) of 50Ω, 100Ω, 200Ω, and 1kΩ
* Integrated Input Clamp
* Integrated Input-Damping Capacitor
* Ultra-Low 2.2dB Noise Figure at RS = RIN = 200Ω
* 70MHz, -3dB Bandwidth

MAX2034 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 matching, which is necessary for high-performance ultrasound-imaging
