2.3.1 TX7516

The TX7516 is a highly integrated, high-performance transmitter for ultrasound imaging systems. The device has a total of 16-channel high-voltage (±100V) five-level pulser circuits,16 transmit-receive switches (referred to as T/R or TR switches), and supports an on-chip beamformer (TxBF). The device also integrates on-chip floating power supplies that reduce the number of required high-voltage power supplies. Figure 2-22 shows the TX7516 block diagram.
