Product Details

The MAX9934T evaluation kit (EV kit) demonstrates the MAX9934T low-voltage, precision, current-sense amplifier for power management in portable consumer electronics. The device's precision inputs and the EV kit's on-board, precision, low-value sense resistor allows the measurement of bidirectional (e.g., battery charge/discharge) currents up to 1A. Input common-mode range is -0.1V to +5.5V independent of supply. The device demonstrates a 25µA/mV fixed gain and the EV kit is configured for a 250V/V gain. The device's chip-select (CS) logic input allows users to multiplex several MAX9934T parts. The EV kit operates from a +2.5V to +3.6V, 100mA DC power supply.

The EV kit can also be used to evaluate the MAX9934F current-sense amplifier. See the Evaluating the MAX9934F section in the full data sheet for more information.
