Handheld ultrasound systems are a recently emerging design in the market, offering a highly compact imaging systems. Handheld probes offer wired and wireless connections and are battery operated, commonly connected to mobile phones while imaging. These handheld probes are similar to portable systems, offering an even higher level of compactness, but at a lower imaging resolution compared to laptop systems. These systems focus heavily on low power, highly integrated transmitters to obtain a pocket-sized design size.

TX7364 and TX73L64, which integrate 64 channels in chip are considered a preferred option for such systems. Both parts offer a current drive of 1A, and are capable of 3-level waveforms, adequate for the basic imaging modes supported by handheld ultrasound systems. For systems that comprise of 128-element transducer array, only two such chips are required for a system, offering a compact system along with a selection of receiver AFE.
