MAX471集成電路（IC）的模擬開關多路復用器解復用器規(guī)格書PDF中文資料

General Description

The MAX471/MAX472 are complete, bidirectional, high side current-sense amplifiers for portable PCs, tele

phones, 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 ground paths of the battery chargers or monitors often found in “smart” batteries.
