MAX4080EVKIT+

The MAX4080EVKIT+ from Maxim Integrated Products is a fully assembled and tested surface mount printed circuit board (PCB) that contains a MAX4080SAUA (8 pin µMAX) IC. The MAX4080 is a high side, current sense amplifier with an input common mode voltage range that extends from 4.5V to 76V. The current sense amplifier provides an analogue voltage output proportional to the load current flowing through an external sense resistor. The EV kit can also be used to evaluate the MAX4081 which is a bidirectional version of the current sense amplifier. The MAX4081's single output pin continuously monitors the transition from charge to discharge and avoids the need for a separate polarity output pin. The MAX4081 requires an external reference to set the zero current output level (VSENSE = 0V). Charging current is represented by an output voltage from VREF to VCC while discharge current is given from VREF to GND.
