Transmitter for ultrasound imaging systems and marine navigation

Mouser now stocks the Texas Instruments TX75E16 16-channel five-level transmitter. Created for ultrasound imaging systems, the device combines on-chip floating power supplies to decrease the required number of high-voltage power supplies. The device is a highly integrated, high-performance transmitter that is excellent for various applications, including non-destructive testing, SONAR, LIDAR, and marine navigation systems.

The transmitter features a pulser circuit that generates five-level high-voltage pulses (up to ±100V) that excite multiple channels of an ultrasound transducer. The transmitter supports 16 outputs and supplies a maximum output current of 2A. The device incorporates all the decoupling capacitors needed for the floating supplies and internal bias voltages, greatly reducing the required number of external capacitors. The device, specified for operation from 0C to 70C, is available in a 10mm × 10mm 144-pin FC-BGA package (ALH package). The on-chip beamformer allows long-duration patterns for Shear Wave imaging. To protect the device from damage due to improper configuration, an internal error flag register can detect faulty conditions and automatically configure the device in shutdown mode.
