Ultrasound transmitter driver

6 July 2011 Analogue, Mixed Signal, LSI

Supertex introduced the MD1712, a two-channel, five-level, high-voltage, high-speed ultrasound transmitter driver IC, designed for portable medical diagnostic ultrasound imaging applications. It can also be used in non-destructive testing and evaluation, metal flaw detection, sonar transmitters and piezoelectric transducer drivers. The MD1712 generates a five-level waveform for CW, PW and colour Doppler images. It drives 12 high-voltage MOSFETs with its two channels, with 1,8 V to 3,3 V CMOS logic interface. The IC features a ±2 A source and sink current for high-resolution imaging, up to 20 MHz output frequency and two separate gate drive voltages to minimise power consumption.
