The ultrasound transmission reference design uses TI's TX7516 five-level pulse transmitter and the high-voltage TMUX9832 switch. The transmitter and switch are connected in a 1:4 manner to address the compact hardware design requirements for high channel count ultrasonic analog front end systems. This design also reduces overall power supply size through the adoption of TI's high-efficiency, small-footprint power modules and SEPIC topologies.
