MAX4172 Datasheet (Maxim) - Low-Cost / Precision / High-Side Current-Sense Amplifier

MAX4172, Low-Cost / Precision / High-Side Current-Sense Amplifier

The MAX4172 is a low-cost, precision, high-side currentsense amplifier for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical.

High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the battery cha
