NCS199A3R数据手册ONSEMI中文资料规格书

描述 Description

The NCS199A3R is a voltage output current shunt monitor (also called current sense amplifier) which can measure voltage across shunts at common-mode voltages from -0.3 to 26V, independent of supply voltage. The low offset of the zero-drift architecture enables current sensing across the shunt with maximum voltage drop as low as 10 mV full-scale. These devices can operate from a single +2.2 V to +26V power supply, drawing a maximum of 80µA of supply current, and are specified over the extended operating temperature range (-40°C to +125°C). Available in theSC70-6 package.
