TX7516 is a highly integrated, high-performance transmitter solution for ultrasound imaging system. The device has total 16 pulser circuits, 16 transmit/receive switches (referred as T/R or TR switches), and supports on-chip beamformer (TxBF). The device also integrates on-chip floating power supplies that reduce the number of required high voltage power supplies.
TX7516 has a pulser circuit that generates five-level high voltage pulses (up to ±100 V) that is used to excite multiple channels of an ultrasound transducer. The device supports total 16 outputs. The maximum output current is 2 A.
Device can be used as a transmitter solution for many applications like ultrasound imaging, non-destructive testing, SONAR, LIDAR, marine navigation system, brain imaging systems and so on.
