General Description
The MD1711DB2 demoboard is as a fi ve-level, dual-
channel, +/-100V, 2.0A, return-to-zero pulser. It can directly
drive two 50Ω 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
external logic signal connector, J13, connects all the input
control signals of the MD1711 to the user’s logic control
source via a short ribbon cable. In typical two-, three- or
fi ve-level bipolar pulsing, PW or CW waveforms can be
generated by the proper input control signal listed below.
Jumpers are provided for the output, such that it can drive
either the on-board RC load 220pF capacitor in parallel
with a 1.0KΩ resistor or with an external load of cable to
the user’s ultrasound testing transducer.
