Overview
The HV748DB1 is used to generate the basic high voltage pulse waveform as an ultrasound transmitting pulser. The HV748 circuit uses the DC coupling method in all level translators. There are no external coupling capacitors needed. The VPP and VNN rail voltages can be changed rather quickly, compared to a high voltage capacitor gate coupled driving pulser. This direct coupling topology of the gate drivers not only saves two high voltage capacitors per channel, but also makes the PCB layout easier.

The AN-H59DB1 generates five output voltages from the 12V input. There are five potentiometers to allow for independent voltage control of each output. The outputs consist of one high voltage positive supply, one high voltage negative supply, one low voltage positive supply, and two low voltage floating supplies.
