AFE5818 Overview
The AFE5818 is a highly-integrated, analog front-end (AFE) solution specifically designed for ultrasound systems where high performance and small size are required. The device integrates a plete time-gaincontrol (TGC) imaging path and a continuous wave Doppler (CWD) path. The device also allows various power and noise binations to be selected to optimize system performance.
