DIO2488B中文资料电压型输出，高边/低边检测，双向零温漂， 高精度电流检测运算放大器数据手册DIOO规格书

描述 Description

The DIO2488B is a voltage output, high-side and low-side current-shunt monitor. The device sense drops across shunts at common-mode voltages from -0.1 V to 30 V, independent of the single supply voltage. Three fixed gains is available 100 V/V. The DIO2488B is designed to use for overcurrent detection, voltage feedback control loops, or as a power monitor. The low offset of the zero-drift architecture enables lower full-scale drops across the shunt and high-precision measurements with very low input offset voltage. The device operates from a single 2.7 V to 30 V power supply or a dual ±1.35 V to ±15 V with low quiescent current. The device is specified over ambient temperature range from -40°C to 125°C, which makes it a perfect solution for industrial and consumer applications.
