Chipset enables high-resolution ultrasound images

The MD1715 and TC8020 ultrasound driver chipset generates a five-level waveform for high-resolution imaging in medical ultrasound applications. The MD1715 is a two-channel logic controller circuit with 12 low impedance, high speed, MOSFET gate drivers. It has two sets of control logic inputs, each set containing three pairs of MOSFET gate drivers which are designed to tightly match the gate requirements of the TC8020.

The TC8020 is the output stage of the pulser, with six pairs of n- and p-channel MOSFETs. It is designed to have high input impedance and provides typical peak currents of ±3.5 A at 200 V and fast switching speed. (Ea/1,000: MD1715K6-G, $3.27; TC8020K6-G, $5.97 — prod qty, 4 to 6 weeks ARO.)
