MAX4080 Evaluation Kit

General Description

The MAX4080 evaluation kit (EV kit) 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

analog 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

Ordering Information

avoids the need for a separate polarity output pin. The

MAX4081 requires an external reference to set the zero-

current output level (V SENSE = 0V). Charging current is

represented by an output voltage from V REF to V CC ,

while discharge current is given from V REF to GND.

All gain versions of the MAX4080 and MAX4081 are

Component List

footprint-compatible and the MAX4080SAUA can easily

be replaced by a MAX4080FAUA, MAX4080TAUA,

MAX4081FAUA, MAX4081TAUA, or MAX4081SAUA.

With a combination of three gain versions (5V/V, 20V/V,

60V/V = F, T, S suffix) and a user-selectable, external

sense resistor, the user can easily match the full-scale

load current to the required output-voltage range.

For maximum versatility, these parts can operate with

76V input common-mode voltage at RS+ and RS- pins,

independent of operating supply voltage (V CC ) used.

These parts also allow a large differential voltage

between RS+ and RS- pins for high reliability. High-side

current monitoring does not interfere with the ground

path of the load being measured, making the
