Integrated analog front ends for ultrasound applications

TI’s AFE58xx family combines multiple high-performance analog components into fully integrated analog front ends, providing superior image quality for a wide range of ultrasound equipment. The devices consume less power and are 50% smaller than comparable devices in the market, while maintaining low noise figures for superior image quality. This helps proliferate portable systems with longer battery life and better image quality. The devices come in an ultra-small 15-mm x 9-mm package.

TI’s AFE5805 analog front end provides low power consumption and lowest noise for portable to mid-range ultrasound systems. The new AFE5804 is pin-to-pin compatible for ease in migration to an even lower power solution, should a design require it. It features mode control to give designers the flexibility to program the level of noise and power performance needed to optimize their system.
