3 Description
The AFE5808A is a highly-integrated, analog front-end (AFE) solution specifically designed for ultrasound systems in which high performance and small size are required. The AFE5808A integrates a complete time-gain-control (TGC) imaging path and a continuous wave Doppler (CWD) path. This device also enables users to select one of various power and noise combinations to optimize system performance. Therefore, the AFE5808A is an outstanding ultrasound analog front-end solution not only for high-end systems, but also for portable ones.
