Texas Instruments Analog Front End IC Part #AFE5808ZCF

The AFE5808A is a highly-integrated, analog front- end (AFE) solution specifically designed forultrasound systems in which high performance andsmall size are required. The AFE5808A integrates acomplete time-gain-control (TGC) imaging path and acontinuous wave Doppler (CWD) path. This devicealso enables users to select one of various powerand noise combinations to optimize systemperformance.Therefore, the AFE5808A is anoutstanding ultrasound analog front-end solution notonly for high-end systems, but also for portable ones.
