General Description
The MAX40010 single-channel, high-side precision current-
sense amplifier with an input common-mode voltage
range from 2.7V to 76V, making it ideal for communications,
automotive, data centers and other systems where high-
voltage current monitoring is critical. The MAX40010 offer
accuracy specifications of less than 12μV (max) Input
Offset voltage and less than 0.1% (max) gain error. By
offering precision offset and gain error specifications, the
MAX40010 makes it possible to sense very small sense/
shunt resistors, further improving system efficiencies and
power dissipation through the sense element.
The MAX40010 features 80kHz of small signal bandwidth
and four unique gain options (12.5V/V, 20V/V, 50V/V, and
100V/V). The device’s current-sense inputs have EMIR
filters to reject RF found in communications equipment.
The MAX40010 operates over the -40° C to + 125°C
temperature range and is offered in a 6-bump, 1mm x
1.5mm wafer-lever package (WLP) with 0.5mm pitch and
a SOT23 U6SN+1 package.

Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
