General Description
The MD1711DB2 demoboard is as a îš¿ve-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 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 îš¿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.
