Ultrasound System Design Advanced With Low-Power Receiver ICs
The AD9278 and AD9279 receiver chips each integrate ADI’s world-leading data conversion technology for low noise TGC (time-gain-control) mode performance while providing high dynamic range I/Q demodulators that reduce the power and area for implementation of CW (continuous wave) Doppler processing. The octal ultrasound receivers provide the highest available output-referred large-signal SNR—up to 67 dB—enabling improved sensitivity in diagnostic ultrasound systems while reducing board space up to 40%.
The AD9278 octal ultrasound receiver is designed for portable ultrasound systems while the AD9279 octal ultrasound receiver is suitable for high-end and mid-range systems. The devices are pin- and package-compatible with each other and allow designers to use a common PCB (printed circuit board) layout that can be leveraged across multiple ultrasound platforms to save development time and cost.
