TX517 (ACTIVE) Dual-channel high-voltage multilevel fully-integrated ultrasound transmitter

 

Description

The TX517 is a fully integrated, dual channel, high voltage Transmitter. It is specifically designed for demanding medical Ultrasound applications that require a Multi-level high-voltage pulse pattern. The output stages are designed to deliver typically ±2.5A peak output currents, with 200Vpp swings.

The TX517 is a complete transmitter solution with low-voltage input logic, level translators, gate drivers and P-channel and N-Channel MOSFETs for each channel.

The TX517 also incorporates a CW output stage.

The TX517 is available in a BGA package that is Lead-Free (RoHS compliant) and Green. It is specified for operation from 0°C to 85°C.

17 Level Pulser Chip:
The chip consists of two 5-level channels to form a single 17-level transmitter cell when used in conjunction with a transformer. It is designed to drive the transducer not only at various output levels, but also to modulate the width of the output pulses to obtain the added flexibility of pulse-width-modulation spectral shaping.
