Evaluation Kit/Master Board for the MAX4940 and MAX4940A

Buy Now View Details

Features and Benefits

  • 3.5mm Scope Probe Jacks
  • Proven PCB Layout
  • Fully Assembled and Tested
  • Stand-Alone Waveform Generation (MAX4940MB+)

Product Details

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 generation, order the MAX4940MB+ together with the MAX4940EVKIT+.

Applications

  • Cleaning Equipment
  • Flaw Detection
  • Piezoelectric Drivers
  • Test Instruments
  • Ultrasound Medical Imaging
