MAX472 Datasheet (Maxim) - Precision / High-Side Current-Sense Amplifiers

MAX472, Precision / High-Side Current-Sense Amplifiers

The MAX471/MAX472 are complete, bidirectional, highside current-sense amplifiers 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 g
