Product Introduction

Overview

The TX7332ZBX, produced by Texas Instruments, is a highly integrated, high-performance transmitter solution designed specifically for ultrasound imaging systems. This device features 32-channel three-level pulser circuits and active transmit/receive (T/R) switches, along with both on-chip and off-chip beamforming capabilities. The TX7332 integrates on-chip floating power supplies, reducing the need for multiple high-voltage power supplies. It generates three-level high-voltage pulses up to ±100 V, which can excite multiple channels of an ultrasound transducer. The device is packaged in a 260-pin NFBGA (ZBX) package with dimensions of 17 mm × 11 mm and operates within a temperature range of 0°C to 70°C.
