MAX4376/MAX4377/ MAX4378 Single/Dual/Quad, High-Side Current-Sense Amplifiers with Internal Gain General Description The MAX4376/MAX4377/MAX4378 single, dual, and quad precision high-side current-sense amplifiers are available in space-saving packages. They feature buffered voltage outputs that eliminate the need for gain-setting resistors and are ideal for today’s notebook computers, cell phones, and other systems where current monitoring is critical. These precision devices are offered in three fixed-gain versions of 20, 50, and 100: GAIN SUFFIX 20 T 50 F 100 H For example, MAX4376TAUK is a single high-side amplifier with a gain of 20.
