DESCRIPTION
The INA193A 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 INA193A operates from a single 2.7-V to 18-V supply, drawing a maximum of 1300-μA of supply current. It
is specified over the extended operating temperature range (–55°C to 125°C), and is offered in a space-saving
SOT23 package.
