Device Overview

Summary

MD1711 is an IC for a two-channel, 5-level, high voltage and high speed transmitter driver. It is designed for medical ultrasound imaging applications, but can also be used for metal flaw detection, Non-Destructive Testing (NDT), and for driving piezoelectric transducers. The MD1711 is a two-channel logic controller circuit with low impedance MOSFET gate drivers. There are two sets of control logic inputs, one for channel A and one for channel B. Each channel consists of three pairs of MOSFET gate drivers. These drivers are designed to match the drive requirements of TC6320. The MD1711 drives six TC6320s. Each pair consists of an N-channel and a P-channel MOSFET. They are designed to have the same impedance and can provide peak currents of over 2.0amps.

MD1711DB2 Demo Board
MD1711DB2 Demo Board ( MD1711DB2 )

The MD1711DB2 demoboard is as a five-level, dual-channel, +/-100V, 2.0A, return-to-zero pulser. It can directly drive two 50 or 75Ω impedance transducers for 1.0MHz to 20MHz medical ultrasound imaging or NDT applications.

The MD1711DB2 consists of one MD1711 in a 48-Lead LQFP package driving six TC6320 complementary high voltage MOSFET pairs in 8-Lead SOIC packages. The...
