8 Detailed Description

8.1 Overview

The INA193

−INA198 family of current shunt monitors with voltage output can sense drops across shunts at

common-mode voltages from

−16 V to +80 V, independent of the INA19x supply voltage. They are available with

three output voltage scales: 20 V/V, 50 V/V, and 100 V/V. The 500-kHz bandwidth simplifies use in current

control loops. The INA193

−INA195 devices provide identical functions but alternative pin configurations to the

INA196

−INA198, respectively.

The INA193

−INA198 devices operate from a single +2.7-V to +18-V 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 SOT-23 package.
