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.
