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.
