3 Description

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

The INA193−INA198 devices operate from a single 2.7-V to 18-V supply, drawing a maximum of 900 μA of supply current. They are specified over the extended operating temperature range (−40°C to +125°C), and are offered in a space-saving SOT-23 package.

(1)Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)Input voltage at any pin may exceed the voltage shown if the current at that pin is limited to 5mA.

8 Detailed Description

8.1 Overview

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

The INA193−INA198 devices operate from a single +2.7-V to +18-V supply, drawing a maximum of 900 μA of supply current. They are specified over the extended operating temperature range (−40°C to +125°C), and are offered in a space-saving SOT-23 package.
