Description

The INA193—INA198 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 INA193—INA198 operate from a single +2.7V to +18V supply, drawing a maximum of 900µA 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.
