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 900mA 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.
