DESCRIPTION
The INA193鈥擨NA198 family of current shunt monitors
with voltage output can sense drops across shunts at
common-mode voltages from 鈭?6V 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鈥擨NA195 provide identical functions but
alternative pin configurations to the INA196鈥擨NA198
(respectively).
The INA193鈥擨NA198 operate from a single +2.7V to
+13.5V supply, drawing a maximum of 900碌A(chǔ) of supply
current. They are specified over the extended operating
temperature range (鈭?0擄C to +125擄C), and are offered in
a space-saving SOT23 package.
