MAX2077
Description
The MAX2077 octal-channel ultrasound front-end is a fully integrated, bipolar, high-density, octal-channel ultrasound receiver optimized for low-cost, high-channel count, high-performance portable and cart-based ultrasound systems. The easy-to-use IC allows the user to achieve high-end 2D and PW imaging capability using substantially less space and power. The highly pact imaging receiver lineup, including a low-noise amplifier (LNA), variable-gain amplifier (VGA), and antialias filter (AAF), achieves an ultra-low 2.4d B noise figure at RS = RIN = 200Ω at a very low 64.8m W perchannel power dissipation. The full imaging receiver channel has been optimized for second-harmonic imaging with -64d BFS second-harmonic distortion performance with a 1VP-P 5MHz output signal and broadband SNR of > 68d B- at 20d B gain. The bipolar front-end has also been optimized for excellent lowvelocity PW and color-flow Doppler sensitivity with an exceptional near-carrier SNR of 140d Bc/Hz at 1k Hz...
