MAX2078 octal-channel ultrasound receiver

Maxim introduces MAX2078 which is a fully integrated bipolar, high-density octal-channel ultrasound receiver . MAX2078 IC allows the user to achieve high-end 2D, PW, and CW Doppler (CWD) imaging capability using substantially less space and power. The highly compact imaging receiver lineup, including low-noise amplifier (LNA), variable-gain amplifier (VGA), and anti-alias filter (AAF), achieves an ultra-low 2.4dB noise figure at RS = RIN = 200Ω at a very low 64.8mW per channel power dissipation.
Main features of the MAX2078 are : 8 Full Channels of :LNA, VGA, AAF and CWD , Pin Compatible with MAX2077 , Ultra-Low Full-Channel Noise Figure of 2.4dB at RIN = RS = 200Ω , Low Output-Referred Noise of 23nV/√Hz at 5MHz, High Near-Carrier SNR of 140dBc/Hz at 1kHz , Offset from a 5MHz, 1VP-P Output Signal and 20dB of Gain for Excellent Low-Velocity PW and Color-Flow Doppler Sensitivity Selectable Active Input-Impedance ( 50Ω, 100Ω, 200Ω, and 1kΩ ) , Wide Input-Voltage Range of 330mVP-P in High LNA Gain Mode and 550mVP-P in Low LNA Gain Mode , Integrated Selectable 3-Pole 9MHz, 10MHz,15MHz, and 18MHz Butterworth AAF .
