(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) Input voltage at any pin may exceed the voltage shown if the current at that pin is limited to 5mA.

The INA194 family of current shunt monitors with voltage output can sense drops across shunts at common-mode voltages from −16V to +80V, independent of the INA19x supply voltage. They are available with three output voltage scales: 20V/V, 50V/V, and 100V/V. The 500kHz bandwidth simplifies use in current control loops. The INA193-INA195 provide identical functions but alternative pin configurations to the INA196-INA198, respectively.

The INA194 operate from a single +2.7V to +13.5V supply, drawing a maximum of 900A of supply current. They are specified over the extended operating temperature range (−40°C to +125°C), and are offered in a space-saving SOT23 package.
