Lead Free Status / RoHS Status
Lead free / RoHS Compliant
19-5273; Rev 0; 7/10
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 25FA/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 for more information.
