      • Description

      The TX734 is a fully integrated, quad channel, high-voltage ultrasound pulser. It can be used in ultrasound applications that require a 3-level high-voltage pulse pattern. The output stages are designed to deliver up to ±2-A peak output currents, with up to ±75-V swings.

      The TX734 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 TX734 supports logic levels down to 2.5 V. It also incorporates an active damping stage for clean RTZ waveform generation. The fast clamping to ground results in high pulse symmetry and low 2nd order distortion.

      The TX734 is available in a QFN-64, 9 mm x 9 mm package. It is specified for operation from 0°C to 70°C.
