APPLICATIONS

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 900

µA 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.
