MAX4940 Evaluation Kit/Master Board
General Description
The MAX4940 evaluation kit (EV kit) provides a proven
design to evaluate the MAX4940 quad, high-voltage
pulse driver. The MAX4940 EV kit can be driven by the
MAX4940 Master Board, a signal generator based on the
Altera EPM1270F256C5N MAX II CPLD.
The MAX4940 EV kit comes with a MAX4940CTN+
installed. Contact the factory for free samples of the pin-
compatible MAX4940ACTN+ to evaluate this device.
For complete evaluation, including test waveform gen-
eration, order the MAX4940MB+ together with the
MAX4940EVKIT+.
