Description
The MAX34406 evaluation kit (EV kit) simplifies evaluation of the MAX34406 quad current-sense amplifier with overcurrent threshold comparators. The EV kit is fully assembled and ready for operation. It is shipped with four 10mΩ sense resistors in parallel on each channel, which creates an effective sense resistance of 2.5mΩ. The EV kit ships with the MAX34406 device installed, which provides a fixed gain of 100V/V. The 2.5mΩ sense resistance and 100V/V gain provide an overcurrent threshold of 4A on each channel. The sense resistors on the EV kit can be changed to adjust the overcurrent threshold. The PCB and the terminals on the EV kit can support currents up to 32A on each channel.
