CURRENT SHUNT MONITOR
−16V to 36V Common-Mode Range
FD EATURES
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).
WIDE COMMON-MODE VOLTAGE:
−16V to 36V

LOW ERROR: 3.0% Over Temp (max)
BANDWIDTH: Up to 500kHz
THREE TRANSFER FUNCTIONS AVAILABLE:
20V/V, 50V/V, and 100V/V

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.
