MAX4073开发板套件编程器的评估板-运算放大器规格书PDF中文资料

General Description

The MAX4073 low-cost, high-side current-sense amplifier features a voltage output that eliminates the need for gain-setting resistors making it ideal for cell phones, notebook computers, PDAs, and other systems where current monitoring is crucial. High-side current monitoring does not interfere with the ground path of the battery charger making the MAX4073 particularly useful in battery-powered systems. The input common-mode range of +2V to +28V is independent of the supply voltage. The MAX4073’s wide 1.8MHz bandwidth makes it suitable for use inside battery-charger control loops.
