Portable systems aim for lower power and size in exchange for a slightly inferior performance as compared to premier and high-end systems. For example, portable laptop systems used in field that are adequate for basic to mid-range imaging requirements but are not capable of advanced imaging modes such as elastography, 3D/4D imaging, advanced doppler modes, and so on. Size and power are critical for these systems and therefore require a high channel integration in the transmitters.

With 32-channels integrated in a single package and a current drive of 2A, the TX73H32 is an option for these systems as the device offers a good balance in performance and area. The device features a 3-level pulser and a high current drive of 2A per channel, the TX73H32 is an option for the imaging modes that portable ultrasound systems generally support.
