MAX4372HEUK

SP Amp Current Sense Amp Single 28V 5Pin SOT-23

General Description

The MAX4372 low-cost, precision, high-side current sense amplifier is available in a tiny, space-saving SOT23-5 package. Offered in three gain versions T = +20V/V, F = +50V/V, and H = +100V/V, this device operates from a single +2.7V to +28V supply and consumes only 30µA. It features a voltage output that eliminates the need for gain-setting resistors and is ideal for today’s notebook computers, cell phones, and other systems where battery/DC current monitoring is critical.
