DESCRIPTION
The INA193—INA198 family of current shunt monitors
with voltage output can sense drops across shunts at
common-mode voltages from −16V to +36V, 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
+13.5V 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.

(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.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
