INA190A2IRSWR General Description
The INA190 is a low-power, voltage-output, current-shunt 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 common-mode voltages from –0.2 V to +40 V, independent of the supply voltage.
The low input bias current of the device permits the use of larger current-sense resistors, thus providing accurate current measurements in the microamp range. The low offset voltage of the zero-drift 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. Five fixed gain options are available: 25 V/V, 50 V/V, 100 V/V, 200 V/V, or 500 V/V. The device is specified over the operating temperature range of –40°C to +125°C, and offered in UQFN, SC70, and SOT-23 packages.
