MAX2079
Description
Benefits and Features
The MAX2079 fully integrated octal ultrasound receiver is optimized for high channel count, high-performance portable and cart-based ultrasound systems. The easyto-use integrated receiver allows the user to achieve high-end 2D and Doppler imaging capability using substantially less space and power. The highly pact low-noise amplifier (LNA), variable-gain amplifier (VGA), anti-alias filter (AAF), analog-to-digital converter (ADC), and digital highpass filter (HPF) achieve an ultra-low 2.8d B noise figure at RS = RIN = 200I with a very low 120m W per channel power dissipation at 50Msps. The full receive channel has been optimized for secondharmonic imaging with an exceptional 76d BFS SNR over a 2MHz bandwidth, and -70d Bc second-harmonic distortion at f RF = 5MHz over the full receiver gain range. Near-carrier dynamic range has also been optimized for exceptional pulsed and color-flow Doppler performance under high-clutter conditions. The bipolar front-end...
