INA190 pdf资料下载The INA190 is a low-power, voltage-output, currentshunt monitor (also called a current-sense amplifier). This device is commonly used for overcurrent protection, precision current measurement for system optimization, or in closed-loop feedback circuits. The INA190 can sense drops across shunts at commonmode voltages from –0.2 V to +40 V, independent of the supply voltage. Five fixed gain options are available: 25 V/V, 50 V/V, 100 V/V, 200 V/V, or 500 V/V. The low input bias current of the INA190 permits the use of larger current-sense resistors, thus providing accurate current measurements in the microamp range. The low offset voltage of the zerodrift architecture extends the dynamic range of the current measurement. This feature allows for smaller sense resistors with lower power loss, while still providing accurate current measurements. The INA190 operates from a single 1.7-V to 5.5-V power supply, and draws a maximum of 65 μA of supply current when enabled; only 0.1 μA when disabled. The device is specified over the operating temperature range of –40°C to +125°C, and offered in UQFN and SC70 packages.
