产品说明

The AFE5809 device is a highly-integrated analog front-end (AFE) solution specifically designed for ultrasound systems in which high performance and small size are required. The AFE5809 device integrates a complete time-gain-control (TGC) imaging path and a CWD path. The device also enables users to select one of various power and noise combinations to optimize system performance. Therefore, the AFE5809 device is a suitable ultrasound AFE solution not only for high-end systems, but also for portable ones.
