Features and Benefits

  • Easy-to-Reach Test Points
  • Fully Assembled and Tested
  • Windows 7, 8, and 10-Compatible Software

Product Details

The MAX40080 evaluation system (EV system) provides a single platform to evaluate the MAX40080 precision digital current-sense amplifier. The EV system consists of two boards connected through headers, a MAX32666FTHR microcontroller board, and the MAX40080 EV kit board. The MAX32666FTHR contains the firmware necessary to use the PC GUI program and provides power to the MAX40080 EV kit board. The MAX40080 EV kit board ships with jumpers preinstalled for quick evaluation of the MAX40080.

Applications

  • Base-Station PA Control
  • Battery Operated Devices
  • Industrial Control and Automation
  • Server Backplanes
  • Telecom Equipment
