MAX4377HAUA - Maxim

<b>Description</b>:<p></p><ul><li>The MAX4377HAUA+ from Maxim Integrated Products is a dual precision high side current sense amplifier with internal gain of 100V/V in 8 pin µMAX package. This device has buffered voltage output that eliminates the need for gain setting resistors. The input common mode range of 0 to 28V is independent of supply voltage and ensures that current sense feedback remains viable even when connected to a battery pack in deep discharge. The full scale current reading can be set by choosing appropriate voltage gain and external sense resistor. This capability offers high level of integration and flexibility resulting in a simple and compact current sense solution. The MAX4377 is used in notebook computers, current-limited power supplies, fuel gauges in PC, general system/board level current monitoring, battery chargers, portable/battery powered systems, cell phones, smart battery packages, automotive current detect, power management systems and PA bias control.</p><p>Supply voltage range from 3V to 28V, operating temperature range from -40°C to 125°C</p><p>High side current monitoring is useful in battery powered systems</p><p>1mA supply current per amplifier, ideal for applications where current monitoring is critical</p><p>±0.5% typical full scale accuracy</p><p>Adjustable current sense capability with external sense resistor</p><p>Buffered output voltage with 2mA drive</p><p>Bandwidth of 1.2MHz and slew rate of 10V/?s</p><p>High accuracy 2V to 28V common mode range, functionally down to 0V and independent of supply voltage</p><p>CMRR of 90dB at 2V ?
