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
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
avoids the need for a separate polarity output pin. The
MAX4081 requires an external reference to set the zero-
current output level (V
represented by an output voltage from V
while discharge current is given from V
All gain versions of the MAX4080 and MAX4081 are
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
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
MAX4080/MAX4081 particularly useful in a wide range
of high-voltage systems.
