Video: Ultrasound Systems Can Produce Clearer Images With TI's New Family of Fully Integrated High-Voltage Pulsers an...(x 9 mm QFN package. Active damping al...),Health

Active damping, also called fast clamping to ground, allows for a clean three-level return-to-zero (RTZ) waveform. This improves pulse symmetry and delivers low second order distortion of -40 dB. The active damping feature in the TX734 prevents noise from being injected into the transducer, which improves signal sensitivity by at least 5 dBc, resulting in better image quality.

The output stages of the TX734 are designed to deliver up to +/- 2-A peak output currents, with up to +/-75-V swings, tailored for portable to mid-range systems. The output frequency of the TX734 is up to 15 MHz and allows customers to take full advantage of higher frequency transducers for far-field images.

Complete signal chain offering for ultrasound designers

TI's TX7xx family of high-voltage pulsers and switches, along with the AFE58xx family of analog front end receivers, offers ultrasound designers a complete and highly integrated analog signal chain for better, more compact ultrasound systems. These devices are complemented by more than 15 embedded processors that support medical imaging applications, including high-performance digital signal processors (DSPs), digital media processors based on DaVinci(TM) technology, and low power OMAP(TM) application processors. Along with TI's power management products, clocks and interfaces, plus dedicated customer support, they comprise a complete portfolio that ultrasound customers can leverage to design their systems.
